9780435093105 - Literacy World Stage 4 Fiction:Cal's Log (6 Pack)
All about two cousins who are stuck inside an enormous stack, after their boat Puffin becomes a ship wreck. It is set in the middle of the sea in a haunted, rock stack. There are plenty of tunnels they explore as well as deathly water pits. I enjoyed the whole adventure of the stack and Cal’s diary, but I loved the words the author used to describe the colossus stack and its hollow insides. However, I got a bit boring because all they do is go round and round the tunnels not much happens until the ending parts of the story. I think it’s a good book good for age 6-12. I'll rate it 7/10.
