Scott and Jo vs The Martians. Scott and Jo Comedy Mysteries, #2

Thirteen year old Jo is proud that her parents have decided that she's very responsible. And then her cousin Scott arrives. He says very little, understands electronics, and loves math. Is it at all possible that he is a robot? Jo isn't sure, but Scott makes clear from the beginning that he's a rational atheist. He and Jo share a passion for getting to the bottom of mysteries, so they end up working together, often while arguing. In Book Two of the series, Scott and Jo confront Martian invaders.
The entire family joins together to help the police chase the Martians out of Mayfair. A story with a lot of comedy, as the Martians seem more playful than dangerous. But darker forces are at work behind the scenes. This time it's Jo who must come to the rescue, as Scott is trapped in a web of danger and deception. Reviewer: "Throughout this book, there are many conversations about faith and why Christians believe what they believe.
In addition to the adventure, this is a brief introduction to Christian apologetics. The author did an excellent job of presenting respectful dialogue between people of different faiths. The perspective is obviously Christina, and yet the author did a good job of not creating a caricature of an atheist. There were no straw men arguments or bad faith conversations. All of the dialogue was centered around caring and respecting people even when they hold different beliefs."
