Query: Run : An excellent installment of the Fearless series.,

Fearless #3, Run , is an excellent addition to this amazing new series -- and continues the adventures of seventeen-year-old Gaia Moore, a girl born without the fear gene. Stalked by a predator she can't see, Gaia desperately goes beyond her measures to save the person she loves -- Sam. The tests and the experiences she must go through to save Sam from his kidnapper are mind boggling. Can Gaia pass those tests? Can she survive them? And can she trust the one person she would never, ever trust in her life -- her worst enemy? Francine Pascal once again writes this book with the dark, beautiful style that she uses to write the FEARLESS series -- and in Fearless #3: Run, it only gets better and better.
