Isola, Vol. 1 by Brenden Fletcher

A loyal captain of the royal guard undertakes a dangerous journey to save her queen, who has been transformed into a tiger, guiding her across a magic-haunted wilderness toward a legendary island said to be the land of the dead and the key to breaking the curse. Pursued by enemies and shadowed by spirits, the pair face treachery, hunger, and doubt, relying on wits and a fragile bond as myth and reality blur.
