As You Wish (Shatterproof Bond #1) by Isobel Starling

1 wedding, 2 best men, one hell of a love story! Declan Ramsay was set to be the best man at his brother's wedding in Scotland, sharing the best man duties with the bride's gay kid brother Sam. Sam was abroad finishing his studies so the best men communicated by email for more than a year and wouldn't meet for the first time until a few days before the wedding But on meeting Sam Aiken, Declan is surprised to see he isn't a kid at all, but a striking, athletic blond man with gorgeous green eyes and a wicked sense of humor. Declan is alarmed by the ferocious attraction he feels for Sam. And as the attraction is reciprocated, the events at Dunloch Castle change everything Declan has ever believed about himself. But is Sam Aiken all he appears to be? Also available in paperback and as an award-winning audiobook, narrated by Gary Furlong.
