There’s this book I remember reading this like 2 or 3 years ago about two kids that accidentally time traveled back in time due to some mistake in a time machine. They just happened to be near the machine at the worst time. I remember the story smoothly going back in forth between the present and the past that the kids were in.
I didn’t get to read much of the book but when the kids were in the past they met some sort of wanderer or merchant maybe. And that person thought they were crazy cause of the way they were dressed and the way they were speaking. Obviously they were foreign.
Scene changes and we’re back with the father and I think they’re panicking wondering where the kids are and they call the cops I think and they get reported missing. All while (well not while but you get what I mean) the kids are traveling with the stranger to the nearest town.
I think this was a trilogy and one of the critique quotes I think compared it to Harry Potter. The cover was a nice art animation style cartoonish, friendly (nice to look at).
