Ancient Guardian — Katie Reus

He lost everyone he ever loved before...Alpha dragon shifter Orion woke from his millennia-long hibernation into a different world—and found a band of humans struggling to survive. He's been living among them, secretly keeping the predators away, but he's kept his true identity hidden from everyone. Until an enemy threatens everything he's come to love, including the human female he's obsessed with. The female he can never have but will sacrifice everything for. Now he has to step up and be the Alpha they all need...Violet fell hard and fast for the stranger who joined their small farming community after The Fall. He lives with them, works alongside them, but there's something different about him that she can't quite put her finger on. When a group of visiting supernaturals upends everything in her community, she discovers he's been hiding a huge secret. But that's the least of their issues. If they don't claim their territory and eliminate the growing threat outside their borders, there won't be anything left to fight for.Author note: Each book in the series can be read as a stand-alone, complete with HEA and no cliffhanger.
