Trouble for Trumpets has been a hit with all my 3 boys. The youngest, now 5 still loves it being read to him. I think the appeal lies in the very detailed illustrations which even adults can look at for ages, and in the story of the Trumpets (peace loving creatures) battling against the baddies, the Grumpets, with all of them looking like strange bears. Combining a very detailed natural history in each picture along with hidden things to find in a fantasy world complete with imaginary weaponry, this book is quite unique. I only wish there were more!
