From time to time they get into trouble and soon they hear that the zoo and their house burned down because of a fire. Their father has to leave so he can help with the house that means Hal and Roger are left alone to tackle some of the biggest and most dangerous species in the world…
Roger is 14 and very funny and cheeky at times but Hal, well Hal is quite different. He is serious, thoughtful, kind but sometimes he does have quite a sense of humour.
I would give these series 10/10 they are so good. I think children ages 7 or over would enjoy these books so if you’re 7 or over and you like adventure books then you’d better get reading!
