My oldest treasure is a beaten-up, pages-falling-out copy of a French wordless book called Patatrac, by Jean-Jacques Loup. It still is one of my most beloved books, and inspired my own Looky Book. Luckily, Mum was a librarian, as it had to be bandaged up and brought back to life many times.
Considering that my normal book pile includes novels by David Mitchell and Neil Gaiman, my greatest guilty pleasure is reading books like Dominic Harvey's Childhood of an Idiot. Not only is it bloody funny, but if you were a child of the 70s and 80s it's an accurate portrayal of, how should I word this ... a much more relaxed style of parenting. I guess you had to be there.
There are many books I've started and couldn't finish. There are way too many incredible books on my bedside table to waste time on things I don't like. However, I have felt compelled to keep some classics, even though I couldn't finish them.
Frankenstein and Treasure Island; they are both great bedtime stories - well, they always put me to sleep before I can read more than a few pages. Nevertheless, I've kept both of them because I own two stunningly illustrated editions by Bernie Wrightson and Ralph Steadman respectively. See, I can still enjoy the great classics, even if the words send me to sleep.
On my daughter's bookshelf is a threadbare copy of AA Milne's Christopher Robin Verses, from 1936, that I inherited from my grandmother. I love Christopher Robin, and EH Shepard's illustrations are delightful. It's a great book to dip in and out of for bedtime reading with the kids. It's a treat to pass on some family traditions, and I've loved sharing my favourites like The Emperor's Rhyme, Bad Sir Brian Botany, the Twice Times Bears, and Pinkle Purr, (whose name I appropriated for one of the kitten characters in my Flying Furballs series).
