Love, Exes, and Ohs: Isaac & Xoey (Cactus Creek) (Volume 4)

She's his best friend, and the woman he never stopped loving... To this day, Isaac McKnight still has no idea why the perfectly-imperfect-woman-for-him put an end to their relationship out of the blue. But he made sure they stayed friends. Now a year later, whether it's at his gym or the dog park they visit every weekend--though neither of them own a dog--he and Xoey are steadily getting sucked deeper into buddy-zone galaxy, with its dangerous proximity to watch-me-settle-down-with-someone-else abyss. That is...until one drunken confession changes everything. He's the world's greatest ex, and the man she can't risk losing... For Xoey Montenegro, history has taught her that sometimes, it's Prince Charming who vanishes without a trace. And fairytale love? Highly overrated. Heck, give her a real and perfect 'oh' over that fantasy any day. So as far as rock-solid tequila-fueled plans for her love life go, coming up with a match-finding formula based on the qualities of the men responsible for her three most epic ohs seems brilliant. The only problem is that one-third of her genius man-quation is all about her best friend Isaac. Also, there is the matter of that fourth epic oh she's kept buried deep in her past. An easy enough thing to keep ignoring... Until her past isn't past tense anymore.
