Summary:  Helga Sharp, an 11-year-old inventor, accidentally makes contact with Erasmus Lope, who’s been trapped on an island where “mad scientists” are exiled away from the mainland.  When Helga is found unconscious on the island, she’s housed with a brother and sister who work as island guards, but who have a few secrets of their own.  With the help of the sister’s robot butler, Helga gets to work trying to free Erasmus.  The secrets of both Helga and the island characters are gradually revealed, as Helga carries out her mission and ultimately finds a new home on the island.  160 pages; grades 3-7.

Pros:  A fast-paced graphic novel with lots of fun characters and plenty of adventure.  The end is somewhat open-ended, and readers will no doubt hope for a sequel to learn about what’s next for the plucky Helga.

Cons:  There was a lot of world-building and plot to cram into 160 pages.
