Lena decides to give up on the Book of Moons when they cannot find anything to help her. While the school discusses the reenactment of the Battle of Honey Hill, Link tells Ethan that Ridley wants to throw Lena a party for her birthday. Ethan does not think that Lena will like this, but Link says that Ridley has already invited the whole school.

The morning of Lena’s birthday, Ethan arrives at Ravenwood. Aunt Del tells him that Lena will not let anyone into her room. Ethan mentally promises Lena that he will love her even if she is Dark. She lets him into her room, and he gives her a birthday present of a necklace with his mother’s ring on it. When Lena comes downstairs, Lena’s grandmother surprises her. Link and Ridley arrive, inviting Lena to the party. Macon forbids Lena from going, even though she wants to pretend that she is a normal 16-year-old girl. Lena and Macon argue when Macon tells her she can never be normal. Lena goes back up to her room. She meets Ethan at the party, explaining that Larkin helped her sneak out. Ethan and Lena dance together and express their love for each other.
