One of the "Trailblazers" series of books on popular non-fiction topics, "Sea Killers" includes a fully illustrated non-fiction section with fascinating information on the topic, followed by a fiction story. The series will appeal to older children and young adults and is particularly suitable for those with an extremely low level of literacy or learning English as a second language. "The Trailblazers" series has been written for older children and young adults with a reading age of 5-8 but has strong general appeal for all children who has just becoming independent readers.

The books are suitable for general reading or as part of a more structured reading programme. Each book is on a strong, popular topic, with a colourful, attractive layout. Each book has a non fiction and a fiction section.

The fiction story appears in two formats - one with simple texts for poor readers; the facing pages contain an illustrated 'speech bubble' version of the same story, for those who are just starting to learn to read. These two levels of entry give access points for children and young adults with different reading ages. The vocabulary of each book is carefully limited, with simple sentences to reinforce reading skills, which make the books suitable for even the poorest readers.

"Sea Killers" tells you what to do if you see a shark in the water, shows you all kinds of poisonous creatures to look out for in the sea, and explains how tsunamis and giant waves are made. The scary story "Shark Attack!" talks about the dangers faced by two divers when they go to explore a sunken boat.
