Wednesdays In The Tower is a sequel to Tuesdays At the Castle. It is not necessary to have read the first book, but it is very helpful. The development of the plot of this fantasy/mystery moved slowly, but it got more exciting as the book continued. The plot was interesting, and I found myself wondering what was going to happen. However, it was lacking an antagonist, or bad guy. There wasn’t really a problem or conflict. Be aware that it ends on a cliffhanger. This really disappointed me, as it was the most exciting part of the book. I’ll be looking for the next book!
