The Winslow family lives by five principles: 1. No one can know your real name. 2. Don’t stay in one place too long. 3. If you sense anything is wrong, go immediately to the meeting spot. 4. Keeping our family together is everything. 5. We wish we could tell you who we are, but we can’t. Please—do not ask…………… Poppy doesn’t know why her family has been running her whole life, but she does know that there are dire consequences if they’re ever caught. Still, her curiosity grows each year, as does her desire for real friends and the chance to build on something, instead of leaving behind school projects, teams, and crushes at a moment’s notice. When a move to California exposes a crack in her parents’ airtight planning, Poppy realizes how fragile her world is. Determined to find out the truth, she mails in a home DNA test. Just as she starts to settle into her new life and even begins opening up to a boy in her math class, the forgotten test results bring her crashing back to reality.

Ingrid can't sleep. She can't remember, either. A competitive diver, seventeen-year-old Ingrid is haunted by what she saw at the pool at a routine meet, before falling off the high dive and waking up concussed. The only thing she remembers about the moment before her dive is locking eyes with Van - her neighbor, former best friend, and forever crush - kissing his girlfriend on the sidelines. But that can't be all. Then one sleepless night, she sees Van out her window looking right back at her. They begin not sleeping together by night, still ignoring each other at school by day. Ingrid tells herself this is just temporary, but soon, she and Van are up every night piecing her memory back together. As Van works through his own reasons for not being able to sleep, they're both pulled into a mystery that threatens to turn their quiet neighborhood into a darker place than they realized.
