Bliss has always been different. Because of a condition called CIPA, she's never felt pain--no headaches, no cramps, no charlie horses. And the worst part? She knows she has an expiration date, and it's probably soon--most people like her don't live past the age of 18. So, what's a girl to do? Well, if you're Bliss, you give the world the finger and live life on your own terms. For her, this means training with her secret agent mom in the art of hand-to-hand combat, and convincing her mad scientist dad to invent a special suit that lets her seek out the world's dangers without biting the big one. But when an old flame from CIPA camp asks her to help track down others like them who've gone missing, her reckless lifestyle is put to the test. Especially when the junior agent her mom assigns to help them with the case turns out to be totally hot--and totally into her. Torn between her feelings of anger toward the life she's been dealt and the one she could have if she let others in, Bliss takes off on a mission that might just be her last.
