Broken-hearted and a thousand miles away from her best friend, Eloise Bloom is alone-something she's never been very good at. Eloise seizes the moment as an opportunity, striving to only show her Best Self. With the help of this alter-ego, she learns to let people in and talk about the Important Things-like her fear of the future and her father who passed away when she was young. Then she meets Trevor, a senior who likes her just the way she is... or at least the way she's trying to be.

Between navigating new friendships and falling in love for the first time, Eloise struggles to figure out if her New and Improved Self is really herself at all. When a shocking revelation rocks her world and leaves her alone once again, she's got no other choice but to answer her own question: who is Just Eloise?
