The Frequency of Aliens

This book was a sequel to The Spaceship Next Door about a small town Massachusetts after the spaceship (from the last book) departed. Similar story arc to the last one where there is a lot of character and plot development and then a lot of action and drama and uncertainty in the last third of the book. Also, like the last book, it wraps up decently with a door open to more sequels.
