What starts as an ordinary summer turns exciting and perilous for twins Ruby and Simon when strange occurrences begin happening on their farm -- sudden gusts of wind, rainstorms, and even tornado warnings -- that seem eerily timed to Simon's emotions. Then a stranger arrives and tells the twins that Simon is a Storm Maker -- part of a clandestine group of people entrusted with controlling and taming the weather -- and that he is in great danger. Soon Simon and Ruby must race against the clock as they try to master Simon's powers in time to stop a rogue Storm Maker's treacherous -- and potentially deadly -- plans. In this thrilling new adventure, loyalties can shift as quickly as the wind . . . and the ordinary can turn extraordinary in the blink of an eye.
