The Infinity Concerto
The first book of a fantasy duology by reknowned Science Fiction author Bear.
It tells the story of a sixteen year old called Michael Perrin. Perrin is bequested a key and directions after the death of his friend, Arno Waltiri. Using the key and following the directions he finds himself in the Realm, legendary home of the Sidhe.
This is an enjoyable fantasy novel, even if the lead character is a bit whiny at times. Strong points include some of the invention in the later parts of the book and the interesting way poetry is used.
Well worth a read if you like your fantasy novels.
