Cute, short book. I love the main characters' names, Xena and Xander. I always thought if I ever had a boy, if he wasn't a "Junior" of his father, I'd want to name him Xander, of course I now like the name Cullen too. Both my names are from my favorite vampire series, Xander from Buffy the Vampire Slayer, and Cullen from Twilight. Anyways, back to the book, Xena and Xander are direct descendents to the great Sherlock Holmes, and they have moved to London, where they meet some people who give them their ancestor's unsolved case book. And of course, they right away choose to solve one of those mysteries. It has to do with a painting that has been missing for 100 years, called "Girl in a Purple Hat".
It's a short, quick mystery, I think kids might like it. And again, as I said with Dodger and Me, it seems as if it will be a series, and you can get kids hooked into reading with series if they like the first one. I don't know that I believe this belongs as a nominee, but who knows what others will think.
For the next book I picked one of the dog books, Leanin' Dog by K.A. Nuzum, there are like 2 or 3 on the list, so we'll see how it goes.
