Young, E.L. The Black Sphere (STORM #3), 299 p. Dial (Penguin), 2009. $16.99. Content: G (mild violence and suspense). The STORM group is on the move again. This time the niece of a dead scientist is asking for their help. Her uncle may have been part of group working to perfect cold fusion – a multinational energy corporation is willing to commit murder to keep the process for themselves. Will has some new gadgets to try while Gaia and Andrew apply their brains to the mystery. All three of the STORM books to date are full of smart kids, dangerous situations and international intrigue. I think they are a lot of fun. MS – ADVISABLE. Cindy, Library-Teacher.
