Magpie by Piper Scott, Virginia Kelly

Reynard Drake, solitary cybersecurity expert and curator of the Drake family fortune, would rather be chucked in the midden than forced to bed an omega, but as the selected Amethyst candidate for the mating experiment, he has no other choice. Resigned to his unhappy fate, he takes solace in the fact that one thing will never change—his virtual rival, Magpie, will always be there to keep him on his toes, even if he has been strangely absent from the internet lately…
Diamond Disgrace Misha Vasiliev has a secret. By day he learns what it takes to warm a dragon’s bed, but at night he’s Magpie, renowned hacker and dark web service provider who steals from dragons in his spare time. His favorite target? Reynard Drake, whom he’s only ever seen in pictures, but whom Misha wants more than anyone else.
And now, with a faceless threat closing in on his cloister, quite possibly the only one capable of saving his life.
