How do people decide on a path, and find the drive to pursue what they want? Ida struggles more than other young people to work this out. She can shift between parallel universes, allowing her to follow alternative paths. How can she know, anyway, whether one universe is ultimately better than another? And what if the continual shifting causes her to lose what is most important to her, just as she's discovering what that is, and she can never find her way back? Ida is an intelligent, diverse and entertaining novel that explores love, loss and longing, and speaks to the condition of an array of overwhelming, and often illusory, choices.
