The Spark is Kristine Barnett's remarkable memoir about being mother to a genius.Kristine Barnett's son Jacob has an IQ higher than Einstein's, a photographic memory, and he taught himself calculus in two weeks. At nine he started working on an original theory in astrophysics that experts believe may someday put him in line for a Nobel Prize, and at age twelve he became a paid researcher in quantum physics. But the story of Kristine's journey with Jake is all the more remarkable because his extraordinary mind was almost lost to autism. At age two, when Jake was diagnosed, Kristine was told he might never be able to tie his own shoes. The Spark is about the transformative power of unconditional love.
