The Partner Disaster by Jenna Fiore

A grumpy jilted groom, a sunshine partner, and an adolescent rooster… what could possibly go wrong?
Trevor’s been with one girl his whole life, and she broke his heart, dumping him at the altar. He’s done with love forever. Trying to pick up the pieces and start over, he’s closed himself off to the world and he intends to keep it that way.

But then a little firecracker named Emily comes crashing into his life, a woman in need of her own fresh start after getting tangled up with the wrong man. She’s smart, gorgeous, and full of energy.
The only problem? They absolutely despise each other.
