Found by Claire Cullen

When Cade and Hunter’s son Brody becomes sick with a mysterious shifter illness, Ollie is ready to do whatever he can to see the alpha toddler well again. His nephew’s illness coincides with the arrival of Toby, an old friend of Max’s. The injured alpha bear is there to deliver a warning; Ajax’s bears and the lions have banded together, and it won’t be long before they set their sights on River Den.
Toby wasn’t sure what he expected when he made his way to the den, but it certainly wasn’t Ollie. The cheerful, bubbly omega is nothing like the picture his people had painted of den omegas. And Ollie seems to have taken an interest in Toby though the alpha doesn’t understand why.

From the moment Ollie sets his eyes on Toby, his omega instinct draws him to the alpha. He knows that where Toby goes, he must go too, wherever that takes him. The alpha bear also has some insight into Brody’s illness, but it’s not good news; to cure him, they’ll need to venture into bear territory, the one place it isn’t safe for them to go. It leads them both on a dangerous journey, bringing them closer together as they work to save Brody, the shifter world, and ultimately, each other.

Meanwhile, Cade and Hunter are facing into the most difficult challenge of their relationship when Brody falls ill. Cade is battling his guilt at not noticing the illness sooner, while Hunter is torn in two directions; saving the shifter world or saving Brody. Allying themselves with the rebel bears leads them to an unexpected discovery; the truth about Hunter’s origins. But will their efforts be enough to save Brody?
