The Sword in the Stone
This delightful retelling of the legend of King Arthur includes a plucky orphan named Wart, a hapless Merlin, a forest outlaw named Robin Wood (Wood, mind you; not Hood)… a delicious platter of medieval treats.
The first book in The Bagthorpe Saga, Ordinary Jack features a family of eccentric geniuses with one ordinary brother. When Jack sets out to raise the morale of a dog named Zero, his plans go up in smoke. And flames. One of my favorite books from childhood.
Another fave. Adams writes an epic of Homeric scale about rabbits seeking a place to call home. The final battle is as gripping as any story ever told.
