Caspian Pumkin-Watts is at the end of his rope. Facing a career crossroads, when he’s offered a chance to spend nine months filming a reality TV show on a French holiday island, he grabs it with both hands.
There are only two problems. His co-star is his ex-husband, and the producer is Caspian’s replacement in his ex-husband’s bed.
Max La Forge of La Forge Oyster Farms knows he’s peculiar.He has a penchant for blue rubber, for instance, and only drinks from a blue mug. He loves driftwood and seashells and hates being touched without his permission. Living alone in his little hexagonal house suits him perfectly, until his dog discovers a young Englishman unconscious on his driveway. Inexplicably drawn to the lonely, complicated stranger, Max garners courage to set out on his first ever romantic exploration.
