Rachel is an alcoholic, struggling to feel better about herself after her husband left her for another woman. Taking the train every morning and evening, Rachel has honed in on a couple's life, and it isn't long before she is deeply embroiled in all sorts of drama. 
 The Girl on the Train is a fast read, one you'll want to keep turning pages as fast as possible until you hit the end. You're likely to figure out the plot before things are revealed, but this shouldn't ruin your enjoyment. Just sit back, hold tight, and gape at Rachel's mess of a life. 
 This book was just the break I needed at the right time, recommended!
