The Gravity Vortex (Vektor Book 1)
by Kynaix
Vektor's teachers gave up on him, until a gauntlet hidden in an abandoned observatory lets him bend gravity. Then a rift tears open and a shadow beast comes through. Thrown back to 1687, he must learn the laws of motion from Isaac Newton himself to save his city. Full-color STEM comic, ages 8-12. Best on a tablet, phone or Kindle Fire.
