Once upon a time, Maggie Cooper lived for adventure. Jumping out of planes was child’s play. Now she can’t even work up the nerve to ask out her coworker. For a bit of self-therapy, she begins to text her recently deceased mother’s phone—the only problem is that the number has been reassigned and for weeks she’s been unknowingly texting a stranger her deepest thoughts and feelings. There have also been some not-so-deep texts, like the ones about her appreciation for her coworker’s butt.
