Royal Alliance by Mckenna James

When Caroline travels to a remote island in order to find a suitable mate for an exiled king, she comes across her biggest matchmaking challenge yet.
King Jamison Reeves is rude and inconsiderate.
Somewhere under that gruff exterior are the bones of a man who’s not bad looking. However, he’s a disaster at dating and shows no inkling of how to court a woman.
Hiding out in a dark and crumbling castle, Jamison plots his return to power. He keeps secrets he’ll protect at all costs, and Caroline not to overstep.
But the more she tries to find the king a match, the more she realizes she’s developed feelings for the difficult man.
After working so hard to find love for others, will Caroline finally find a happily ever after of her own?
