Wolf Bite - TJ Nichols

After four years of living in Darwin, George Franklin is back in Melbourne, and everything has changed. There is now a pack of gay wolf shifters with their own territory, something that would have been unimaginable when he left. His own family pack is expecting him to move home and run with them.and he definitely doesn't want to do that. The last thing he wants, though, is to fall for his best friend's older brother—again.
Pack and family come first. Evan Steele knows that, and because of it, he lived a lie for years. He did things he regrets on the pack leader's orders. Now, he's put as much distance as he can between his past and his present. To humans, he is successful and confident. But he hates shifting. He hates running on four feet.
When his past turns up at his door in the form of an anonymous hook-up, Evan's lies come unstuck, and he'll have to choose between putting himself first or obeying the pack who will hate him if they knew the truth.

This is the final book in the mm wolf shifter Outcast Pack series.
