What would you say to your meddling parents, your ex-best friend, your toxic boss, or your high school crush if you didn’t have to face the consequences? Sara Chae is the founder of One Last Word, an app that allows you to send a message to anyone you want after you pass. Safeguards are in place so the app will only send when you’re definitely, absolutely, 100% dead, but when another Sara Chae dies and her obituary is posted online, Sara discovers that drafted messages she had drunkenly uploaded on one night have been released—one each to her emotionally charged mother, to her former best friend who ghosted her, and to her unrequited high school crush, Harry Shim.

Still reeling from this disaster, Sara finds out she’s been accepted into a venture capital mentorship program—and that the mentor she’s been assigned to is none other than Harry, who’s now a major VC superstar. With her life going from uncertain to chaotic overnight, Sara has to deal with the havoc that ensues and reopen wounds from the past to find a true path forward.
