I finished this book quickly. It reminded me of Bridget Jones in some way -- probably tone, and the age of the protagonist.The heroine has just been involved in a car accident; she was driving. With her was Marilissa, a 24 year old woman she had just met in a Weight Watchers meeting. She has an accident (not really her fault) and Marilissa dies. Fast forward 6 months, and nothing much is happening in her life still, but she goes to the grave. There, she meets Marilissa's brother Troy, and commits to completing the remaining 18 of 20 items on Marilissa's list of things to do before I'm 25, which she found at the accident scene.Now she has a focus, and a lot starts happening in her life, and a lot of people enter it. She becomes a Big Sister to a troubled 14 year old, tries to advance at work in spite of a spiteful boss, tries to find romance, all the while completing Marilissa's list.
