When his twin sister commits suicide three days before their birthday, Leonard Collings is thrown into a whirlwind of pain, sympathy, and unbearable pity. Teachers and friends begin to treat him as glass, and his parents can barely speak to him. Students he doesn't know give him their condolences, even if they didn't know Annabeth themselves. People feel sorry for him. And he hates it. Leo, along with his best friends Jeremy "Bear" Michaels and David Kelley, tries to navigate his way through high school and life with a large piece of himself missing, something that will never come back. When the trio finds the bucket list the twins made years ago, Leo becomes determined to complete the list for Annabeth, no matter what the consequences.
