Where Did You Go?

""Maybe I want to be everything to you...your hero and your villain antied in the In-Between, Caly, Mendax, and Aurelius are fighting for their lives--they just don't know whose. Caly's bond to Mendax from their bonding ceremony and her mortality being tied to Aurelius's from when he saved her life mean the three of them have tangled their life forces together. And now that they know maintaining both connections is against the natural order of things, one of them must be sacrificed for the other two. Caly can't let another one of her loved ones die, but she also needs to answer the summons so she can finally meet her father. Then, perhaps, she can be sent to the Elysian Fields to be with her mother and sister. But her father has information that could change everything--and even if she's ready to sacrifice herself, she'll have to get through the Seelie Prince and the Unseelie Prince to do so, while also keeping them from killing each other."--
