As a reading addict, I was wondering if we could recommend a few books to each other.

My recommendations would be:

CS Lewis 'The Horse and His Boy'; one of the Narnia books, it's about how a boy is taken under the wing(?) of a talking horse and their adventure together. Although the AF is a horse, it is a BL story IMHO.
(Of course ALL the Narnia books are great, but this is the only one with an adult / child relationship at its core.)

Orson Scott Card's 'Songmaster'. A very powerful presentation of the love of a man and a boy.

Stephen King's 'Dark Tower' series. Whilst the BL relationship is only one sub-plot in the story, it's a great tale.
