The phrase you provided appears to be a scrambled or fragmented version of a statement about the order of Colleen Hoover’s novels It Ends with Us and It Starts with Us. The commonly understood idea is:

• It Ends with Us is the first book in the pair.
• It Starts with Us is a sequel (not a prequel) that follows events after It Ends with Us.

If you’re asking which comes first and how they relate, here’s a concise guide:

• First book: It Ends with Us. It introduces Lily Bloom and the central relationship dynamics, and it ends with a pivotal decision that shapes the characters’ futures. This is generally considered the book to read first.

• Second book: It Starts with Us. This continues the story from Lily’s perspective after the events of the first book, focusing on the aftermath and further development of the relationships, but it is not a direct prequel. Readers typically read It Ends with Us first, then proceed to It Starts with Us.

If you’re looking for confirmation on the recommended reading order from fans or sources, most discussions and official descriptions indicate:

• Read It Ends with Us before It Starts with Us. This sequence preserves the narrative timeline and character arcs as intended by the author.
