[octopusinasantasack]

DS (8) was reading a book at school called something like Dark Secrets, it's got a picture on the front cover of a person under the ice breaking through. He doesn't know who it is by and I can't find it on Amazon. Does anybody have any idea what it might be please? He enjoyed it so wants to read more that are similar.
Thanks.
