I almost didn’t do this one because I had a HARD time coming up with an answer that didn’t also give away the second book.
Alexandra has come to the realization that she will never see Garrick again and has also lost her best friend. She decides that as long as Felix has her, he has a hold over Garrick and he will never let him move forward. She decides to take action to end Felix’s hold the only way she knows she can control.
