Thanks in Advance by S. M. James

When Rory flies from America to Australia for a surfing comp he has no hopes of winning, he thinks the highlight will be few weeks off school. But staying on the farm of some family friends introduces him to Justin, who’s cute, quiet, and totally unreadable.
They say opposites attract, but Rory and Justin aren’t even in the same stratosphere.
Justin is skittish and reserved, hiding a world of secrets behind his odd-colored eyes.
Rory is vibrant and energetic, trying to make the most of every moment. It’s why he’d said yes to this adventure to begin with.
With foaling season in full spring, and the Australian spring stretching out before them, the birth of a foal gives Rory a peek into the guy behind the mumbled words and adorable blushes. When Rory starts to bridge the distance between them, common ground doesn’t seem so impossible.
Justin needs to challenge his social anxiety and experience the bigger moments in life, but can he let go of his world long enough to let Rory in?
