TALES OF THE NINE: APOTHECARY by JL Lahey

A young ranger accepts an offer to join a band of eight adventurers, currently on a mission to hunt down evil relics stolen from a Paladin orders stronghold.
As the fellowship of greedy, secretive, quick to anger, overly violent, hormonally driven adventure seekers, proceed on their quest, their efforts are repeatedly hampered by obstacles that seem totally random.
After a pack of huge hairless wolf like creatures attack the town the group is staying in, they have to consider the possibility that someone or something might be behind all the evil that they have been facing.
As deep winter approaches and through encounters with bandits, slavers and foul beasts, the band also has to contend with the knowledge that one of their number might have become tainted by the very evil that they are now hunting.
