Worf and Algy Lacey mention Alex Kimbell's "Think like a Bird", which is indeed excellent.
Kimbell has also written a subsequent book called "The Unbridgeable Divide", which is well worth a read itself and is easily available in pbk ISBN: 1-899293-19-1
It is subtitled "A Love Story", and the jacket blurb can give the impression that it strays into the worst of Richard Bach territory. Maybe it gets close to that, but only in a very limited way on a couple of occasions. Don't let either of those things put you off though - I enjoyed it very much.
However, it has been proof-read appallingly...
