All the Wrong Shelves by Felicia Blaedel

Nessa Ravn couldn’t have picked a better time to look for a library ghost.

Zander is making the right decisions to fight the indifference that has shaped his life. When one of those decisions leaves him temporarily homeless, he never expected to gain a new friend.
Nessa is real, she’s honest, and she believes in him. Zanders longs to be authentic. He’s been pretending, playing a part, for as long as he can remember.
But Nessa is pretending, too. Pretending she isn’t exhausted, that the world isn’t too loud, and that she doesn’t have a book full of notes that might explain why she’s always been a little different.
As she’s learning to trust herself, she might even realise that she doesn’t need to hide who she is.
They’re unexpected roommates, unlikely friends and maybe something more — something real.
