The Warrior Princess by Renee Carr

A rogue attack. A shocking kidnapping. A surprise fated mate.

Joshua, the Crown Prince and Captain of the Guards, doesn’t want to fall in love, but fate has other plans for him… so do rogue wolf shifters.
Leah enjoys the time she spends with her longtime friend and fiercest confidante, but when time and circumstance push them to the edge, she discovers Joshua is much more than her good friend.
When the wolf shifters attack the Royal Palace, Joshua’s world is turned upside down. His brother kidnapped. His throne in jeopardy. His fated mate now must fight by his side against insurmountable odds on a planet with little chance of escaping.
