Her Pirate Prince by Joanne Wadsworth

The Mediterranean isn’t safe.
An irritating fact to be sure, but that won’t stop Prince Anteros from showing his new wife around his Mediterranean island of Paradiso. His island borders the volatile sea where the Barbary corsairs reign, or at least they did reign. He now does, and he won’t allow any corsair to step foot on his land. Unfortunately, it appears one corsair has, as well as now stolen his wife right out from under his nose.

That corsair clearly has a death wish.
Furious, Anteros sets out to engage in a battle like no other. He intends on destroying the man who has gotten in his way, retrieve the woman he loves then ensure every single enemy he has (of which he has plenty) understands the brutal lengths he’ll go to, to keep his loved ones safe.
Death wishes, hopefully, can be dealt with.
