Just 2 new ones this week and both of them are middle grade.
Tunnels by Roderick Gordon and Brian Williams - first in a series that I "bought" with points. The boys need to be reading harder books and this one looked fun.
Nick and Tesla's Robot Army Rampage by "Science Bob" Pflugfelder and Steve Hockensmith - provided a copy by Quirk Books for review. This is the second in a series.
