Fated to the Alpha and the Angel - Palace of Souls, #1

The Palace of Souls is a safe haven for the global supernatural community and caters to every being that could possibly walk through its doors.(There are even rumours that the Palace hosted Elvis once - after he died.)The Palace also provides every service a supernatural being could want. Need a Fae hooker for your bachelor party? The Palace has got you. Need a fertility spell for your one night with that billionaire werewolf? No sweat.
Need a five-hundred-year-old curse-broker? Just a second. The first in a series, Fated to the Alpha and the Angel, is the story of Catra, the Palace's sexiest and most powerful witch. Her paths cross with Daniel, a human curse-broker, while she is deciding whether to reject her eternal, destined mate, Ryan - a powerful, Irish Alpha werewolf. Their worlds collide when Catra turns Daniel into an Angel instead of a demon and they must flee London with Ryan's help.
Things become slightly more complicated when the three realize they're all mated to one another and are the first set of triad mates in decades.
