Graystripe's Adventures, by Erin Hunter, is actually a set of three graphic novels centering on the warrior cats who are also featured in Hunter's novels, Warriors. These three books (The Lost Warrior, Warrior's Refuge, and Warrior's Return) chronicle the life of the ThunderClan deputy Graystripe after he is kidnapped by "twolegs" (humans). His story begins after he has been taken to a twoleg house. He has plenty of food and shelter, and the twolegs are kind to him, but Graystripe can't forget his home in the forest. So he sets out for home, and along the way is joined by a friendly housecat named Millie. They meet several unlikely new allies and face difficulties that will push both of them to the limit...but they are both in for the ultimate shock when they arrive at the forest to find it...destroyed. Can Graystripe and Millie use their tracking skills to find what remains of ThunderClan, or is this the end of the road for them?
I really enjoyed these graphic novels. They were nice and quick, certainly not time-consuming at all. If you've read the original Warriors books, I'd definitely recommend these to you. However, if you haven't, don't read these yet--wait until you've read Warriors first!
