Magda Miller's feud with rival baker Mackenzie Newton is so old, folks in tiny Pine Hollow, Vermont forgot how it started. But Magda remembers: Ten years ago, she offered Mac her heart--instead, he ran off with her grandmother's maple cake recipe. Now, Mac traipses all over Magda's baking territory, just like his oversized tabby keeps sneaking into her house to claim her dog's favorite bed. So, when Magda gets the call to compete on The Great American Cake-Off, she's thrilled to finally shine in a Mac-free zone. But when she arrives on set, her devilishly handsome nemesis is already there . . .

It turns out, Mac and Magda's story has inspired the first ever Arch Rivals edition of Cake-Off, and of course Mac has to raise the stakes with a wager. The winner takes all--the Cake-Off title, the contested recipe, and control of the narrative. Magda is more than ready to kick Mac's Bundt. But as they spar, on-screen and off, Mac and Magda reveal the best in each other...and the sizzling attraction fueling their rivalry. Only one of them can win, so why does it suddenly feel like they both stand to lose?
