Eric O'Shea needs to make a decision. The annual event his family forces him to attend is just around the corner, and he doesn't have a date.
Eric never needs help when it comes to finding men. But this time is different – his ex and his new boyfriend will be there, and Eric can't just bring along one of his usual flings.
His only hope seems to be him: the best friend of his best friend, who he never wanted to meet.
Sean Quinn is a calm, collected, and cultured man; someone who would rather stay at home and read a book than waste his time chasing a date with no future.
Sean isn't in a rush to find the perfect man, and he certainly doesn't intend to go out with Eric: his best friend's other best friend, who he's avoided meeting for years.
But Sean has a flaw: he can't say no to anyone, especially not when it comes to his friend Jake, who has a habit of worming his way into other people's lives.
But it's just one date, after all: pure fiction. It's a shame, then, that when Eric needs Sean for another favour, he can't turn his back. It's a shame that just when Sean is beginning to understand that Eric isn't what he seems, he can't seem to stop before he gets hurt.
Twenty-one days: that's the agreement.
Twenty-one days of grazing hands, furtive glances, and unexpected kisses.
Twenty-one days where anything goes; except falling in love.
