Atlas Corrigan is a supporting character in Colleen Hoover’s novel It Ends With Us who reappears in the sequel It Starts With Us. In the story, Atlas is a former Marine and the ex-boyfriend of Lily Bloom, the protagonist of the first book. He enters the narrative primarily through Lily’s memories and present-day interactions, serving as a catalyst for her emotional growth and a contrast to her current relationship with Ryle. This article explains Atlas’s background, his role across both books, and why his presence matters to the series’ treatment of love, choice, and healing.
Who Atlas is and what he does in the story
Atlas Corrigan is introduced in It Ends With Us as a Marine stationed near Lily’s hometown. They meet briefly during a difficult period in Lily’s life, and their connection is intense but short-lived. Years later, Atlas reappears as an adult in It Starts With Us, where he is depicted as a former military member who has left the service, is working to rebuild his life, and maintains a quiet, guarded demeanor. He is not a viewpoint character; the story reveals him largely through Lily’s perspective, memories, and the impact of their past on her present decisions. Atlas functions in the narrative as a symbol of an unfinished chapter and as a touchstone that tests Lily’s understanding of love and safety.
Timeline of Atlas in the two books
| Book | Stage | Narrative function | Key emotional role |
|---|---|---|---|
| It Ends With Us | Brief adult encounter in the present | Forms part of Lily’s backstory and her emotional history | Represents a powerful but volatile connection and the question of what might have been |
| It Starts With Us | Reunion in the present day | Tests Lily’s growth and current commitments | Highlights the contrast between intense past attachment and the deliberate, accountable love she chooses with Ryle |
Atlas’s role as a narrative device
Within the series, Atlas operates as a memory structure and a narrative device that allows Hoover to explore how early, intense experiences shape later choices. Because he is not present in every scene, his influence is felt through Lily’s internal conflict, her conversations with Ryle, and her reflections on what she wants from partnership. Atlas is not positioned as a villain; his behavior in both books reflects his own trauma, military background, and personal limitations. By contrasting Atlas with Ryle, the story emphasizes the difference between compulsion and conscious partnership, making Atlas a benchmark against which Lily’s growth and commitment are measured.
His relationship with Lily: contrasts and significance
Atlas and Lily share a bond defined by intensity, honesty about pain, and mutual attraction. However, their relationship lacks the safety, reciprocity, and long-term planning that define her connection with Ryle. Where Ryle and Lily build a shared life with explicit communication and negotiated boundaries, Atlas and Lily orbit each other around unresolved history and strong feelings. This contrast helps Lily articulate what she needs from a partner: reliability, respect, and the ability to handle conflict without retreat. Atlas’s presence therefore deepens the series’ exploration of how people move from powerful but destructive patterns toward healthier love.
Themes Atlas brings to the series
The character of Atlas lets Hoover address several core themes across the two-book arc:
- The seduction of intensity: Atlas embodies the appeal of overwhelming emotional connection, showing how magnetic chemistry can overshadow practical compatibility.
- The role of choice and accountability: Lily’s eventual commitment to Ryle underscores that love is not only about feeling intensely but also about choosing someone consistently and responsibly.
- Healing from past trauma: Atlas’s military background and guarded nature provide a lens for discussing how personal history shapes relationship patterns.
- The difference between nostalgia and compatibility: Atlas represents a version of Lily’s past that feels vivid but does not necessarily fit her future.
How readers and critics interpret Atlas
In reader discussions and critical reviews, Atlas is commonly framed as a symbol of the past that the protagonist must honestly confront rather than return to. Reviewers note that he is not a traditional antagonist but rather a mirror that reveals how Lily has changed. His quieter, restrained presence compared to Ryle’s forceful personality emphasizes the value of steady, communicative partnership. Although some fans are drawn to the romanticized version of Atlas from Lily’s memories, the series ultimately frames his role as necessary but insufficient for the life Lily builds by the end of the second book.

Atlas versus Ryle: a contrast in partnership
Atlas and Ryle represent two approaches to love that the series places in tension. Atlas’s connection with Lily is rooted in intense feeling and shared pain, while Ryle’s is built on communication, boundary-setting, and long-term planning. This contrast does not vilify Atlas; instead, it clarifies what Lily learns about herself: that intensity alone does not sustain a safe, evolving partnership. By the end of the series, Lily’s choice reflects her growth from seeking thrilling emotional highs to valuing steady, negotiated commitment.
Why Atlas matters to the series’ emotional arc
Atlas matters because he represents the kind of love that feels consuming and true in the moment yet ultimately falls short of the reliability and mutual growth that Lily comes to value. His presence allows Lily to test her boundaries, articulate her needs, and recognize the difference between being understood in a storm and being supported through everyday life. In this way, Atlas functions as a necessary contrast that deepens the reader’s understanding of love, healing, and responsibility across both books.
Atlas in It Ends With Us and It Starts With Us is best understood as a memory figure whose role is to highlight Lily’s journey from intensity to intention. He is not the endpoint of her story but a milestone that clarifies why the careful, accountable love she builds with Ryle is central to her growth. By revisiting the past and choosing the present, the series frames Atlas as important not for what he offers in the future, but for what he teaches about moving forward with honesty and care.
