The novel focuses on Auden West, who never sleeps at night due to her parents' continuous fighting when she was in high school.

Auden also ends up spending her nights making up for her lost childhood with Eli, a loner and insomniac with an intriguing past.

Auden West is an academically accomplished girl who didn't get the chance to enjoy the activities young children often got to do (such as riding a bike) when she was a child.

After being accepted into Defriese University upon graduating high school, Auden is not sure on how to spend her summer.

After receiving a package from her brother Hollis who is touring Europe, she decides to take up her father's offer to spend her summer before college in the beach town Colby.

Once they figure out who he hooked up with, Auden ends up briefly explaining to Maggie that she has no relationship with Jake whatsoever.

Heidi has to go to her boutique on the way to dinner due to a business error, which irritates Auden's father even more.

While waiting for Heidi at the diner, Auden is prompted by her father to take care of Thisbe outside.

Jason asks Auden to go with him to the Beach Bash, an event Heidi had planned for the end of the summer.

However, when Eli and Auden meet again, they talk things out and decide to go to the Beach Bash together and have a great time.

At the end of the book, Auden has started university and is at Ray's, a diner she used to regularly visit when she had insomnia, with Eli.
