The Wild Hunt by Apollo Surge

Sawyer has only just started to get used to being a shifter and part of a pack when a revelation about his place in that pack leaves him shaken and angry. Sawyer is an omega. In the service of his role, he’s expected to bond with a mate and raise children to rebuild the pack’s waning numbers. No one is surprised by Sawyer’s vehement refusal. But fate seems determined to ensure he’s mated. Alphas from other packs appear, all with their own ulterior motives for ensuring Sawyer is mated to them, despite his adamant refusal to bond with anyone, and a sinister fact of shifter biology makes it more difficult for Sawyer to resist their advances with every passing day. Meanwhile, Duncan, Alpha of the pack, has fallen into drunken despondency over the death of his mate and the pack is in chaos, while a darkness they thought already dealt with gathers itself to break free, and Sawyer may be the only one capable of stopping it, for reasons even he doesn’t fully understand.
