Grinding by Sean Ashcroft

Two childhood best friends. One accidental fake engagement. One Labrador puppy. One week to fall in love.

When Harvey runs into his childhood best friend—literally—on the way into Otter Bay for his cousin’s wedding, he doesn’t plan to end up playing the part of the guy’s fiancé. But one trip to the hospital and one tiny white lie later, and the whole town knows he’s engaged to Iggy Beaumont, everyone’s favourite barista and all-round sweetheart.
After being left at the altar by the guy Harvey once told him wasn’t good enough for him, Iggy’s heart still hasn’t mended. He’s not ready to date yet, but when Harvey offers him a no-strings-attached deal, he jumps at the chance for risk-free affection from someone he trusts.

All they have to do is avoid falling in love. How hard can that be?
They’re only each other’s first ever crush, after all…
