Promised to the Mountain Man by Aria Cole

Under the stars, passion blazes as bright as the constellations in this age-gap, best friend’s little sister, mail-order bride love story…

Ridge Warner has sworn off love. An ex-military loner with a passion for the stars, he spends his nights charting constellations from his observatory on Devil’s Peak and his days teaching snowboarding at the lodge. Practical, quiet, and fiercely independent, Ridge is content to keep the world—and romance—at arm’s length.
Until a mail-order bride ad changes everything.
Quinn Stevens isn’t your average bride. A brilliant researcher with a fiery personality—she’s not looking for a husband— she’s looking for answers among the stars. When she arrives on Ridge’s doorstep thanks to a prank pulled by his mischievous brother, Zane, sparks fly. Ridge is annoyed, Quinn is unimpressed, and the chemistry between them is undeniable.
As their shared passion for the night sky and snowboarding draws them closer, Ridge can’t resist the way she turns his carefully ordered world upside down—and the overwhelming desire to make her his. But Quinn is off-limits because she also happens to be Ridge’s best friend’s little sister. But when Quinn’s research into a rare constellation stirs up trouble with powerful enemies, Ridge’s protective instincts kick into high gear.

Will Ridge let go of his fear to commit and claim the woman who’s captured his heart? Or will the stars align to pull them apart forever?
