Those kids are back – all of them plus two new Maori friends – for a new environmentally-aware and Ransome-inspired adventure that starts when they discover a wounded seal.

In Those Seal Rock Kids, his fifth book in this Ransome-influenced series, Jon Tucker deftly marshals the original kids – Jess, Jake and Fin, plus friends Tania and Zac, with the two smart girls from the sugar-barge, Ella and Sam – along with their Maori chums, Johnny and Heeni – who have to face problems of their own that threaten to turn their lives upside down.
