The Snowball Effect by Holly Nicole Hoxter
(no cover yet)
18-year-old Lainey Pike can tell you everything you need to know about the people in her family just by telling you how they died. Her reckless stepfather drove his motorcycle off the highway and caused the biggest traffic jam in years. Her long-suffering grandmother lived through cancer and a heart attack before finally succumbing to a stroke. And Lainey's mother, still devastated over her husband's death, hung herself in the basement just days after Lainey's high school graduation. Now Lainey's five-year-old brother is an orphan and her estranged older sister moves back home to act as his guardian. Dealing with her brother has always been a struggle, but sharing the responsibility with her sister is proving to be just as challenging.
Lainey knows that this is all her mother's fault, but she also knows that she eventually has to move out of the "anger" phase of the grieving process. What she can't figure out, though, is how to make peace with a dead woman.
