Even though I realise I'm very very late in discovering this, I have only just done recently. However, upon such a delightful find, I immediately got a copy of the first book as a present for a friend on his birthday. I hope he likes it as I'm aware this may not be everyone's cup of tea. Definitely mine.
The very original trials and tribulations of these self-destructive bunnies really make me giggle. Have to check out Mr. Riley's other work 'cos this is dead promising.
