The Insect Vegetable Wars - Raymond C Wood - Bog

In this third book in a trilogy of witchcraft, following Underneath Rockville and Baby's Sofia's Reckoning.
Satan unleashes millions of rogue insects and vegetables to tear into humankind, spreading deadly diseases in an intense chess match with God, as He counters with an army of praying mantises. As the battle between good and evil rages on, who will maintain control over human souls?
And yes, Lyla, you did hear voices underneath the vegetable garden!
