Final instalment in a rip-roaring funny magical adventure from the author of the FROGSPELL series!

Join Jem and Dora, Simon and Cat again as they hunt for the sea amber - the final piece of Deep Amber - which they must locate before the evil Lord Ravenglass can find it. If it falls into the wrong hands, the owner could forge a powerful crown of amber, and use it to rule and destroy the World Tree...

Another pacy magical adventure full of action and humour as our young heroes race between different worlds!
