Abundant Moon by Alexander Elliott

Gladstone is preparing for an invasion – of pups! With five little ones on the way, Ben and Evan have their hands full with first-time parents, a daring winter rescue, and disturbing information from Hezekiah’s journals. If that weren’t enough, a visitor arrives with a troubled past and a bond gone awry. Their only hope lies with a risky True Elder intervention that’s never been tried and could end in tragedy.
