Quite often reading a novel requires a certain suspension of belief. Fantasy and science-fiction are usually not realistic, but many ordinary stories also contain elements of fantasy. As much as we might wish to receive an admission letter to Hogwarts we know it's not a real place, and that Uncle Vernon was unfortunately right when he said "there's no such thing as magic." But we accept this alternate reality within limits because it's entertaining. You don't have to believe in vampires to enjoy Dracula or the Twilight series. As long as the story doesn't contradict the real world in an unbelievable way and the characters act appropriately for their age, time, and setting, there's no problem. Tom Sawyer and Tom Fitzgerald (The Great Brain) are not grown-up and they get into the kind of mischief you'd expect from kids their age. It's part of what makes reading so much fun for many of us, and we get to spend a few hours in another world or remembering what it was like to be young. But when a kid in a book starts talking and acting like an adult and doing the kinds of things an adult does, it breaks that spell.
Several years ago we listened to a thoroughly charming book when we went on a family vacation to Moab, Utah. I'd gotten tired of having to switch out movies for the kids every couple of hours during the drive and thought an audiobook might be a nice change. I read a review for Nick of Time by Ted Bell and it sounded like the perfect story for a road trip.
With Nazis and pirates and time travel and danger and heroism it has all the elements of the great adventure stories I read as a kid and it kept the whole family interested through a long drive. None of us knew anything about sailing or nautical terminology but it was a fun adventure story with some real history mixed in (be warned, however, that the brutality and reality of sea battles may not be for the faint of heart). So, when I saw The Time Pirate: A Nick McIver Time Adventure (#2) I thought it might be another fun story.
So, I'll recommend Nick of Time as a fun adventure story but I'll recommend skipping the rest of the series.
