The Dragon Lord's Love: The High Garden Dragons 8

A lonely, 4,000-year-old dragon discovers his fated mate… too bad his mate is engaged to a woman.
The endless stream of lovers, dragon lord Matías Tilly parades through his life hasn’t helped him feel less alone. Finding his fated mate should help him escape his loneliness. At least, that’s how it’s supposed to work. Unluckily for Matías, his mate’s happily engaged to be married… to a lovely woman.
Ryan Hall has always sought his father’s approval; every decision in his life stems from him trying to be good enough. The validation he craves never materialized. It has, however, led to an engagement to his best friend. Except… they’re both gay.
When the two meet, Matías must face that his heart is bound to another. Ryan must struggle with the thought that being true to himself might cost him everything. Oh, and Ryan doesn’t know that Matias is a dragon shifter, so that’s going to be a surprise.
