The Spring Prince by Delaney Rain

Bridge Flint just wanted to spend time with his life-long best friends but instead finds himself falling through a fairy ring and into a pool where a naked fae prince was just about to enjoy a swim. Bridge is in the Spring Court with absolutely no way to get home.
Determined to make the best of it, he accepts a job, learns about the curse trapping everyone within the court, and tries to discover if his friends have also come through the ring. He’s also getting to know the prince and wondering if boosting his confidence to regain control of his court will help break the curse. Falling for him? Bridge can’t resist a sweet man who grows flowers in his hair when he’s happy.
Standing in the way of that happiness is a former advisor who’s usurped the prince’s throne and has grown increasingly dangerous. Can Hydris learn to stand up to those who would keep him down? Could that be what frees everyone?
And what about falling in love?
