How did she take a peek? Aren't her compound eyes omnidirectional? Or are the ommatidia directed in facing direction so small and densely packed, that she has a high viewing resolution there, similar like the Macula in the retinas of us humans? I guess she would need that feature, if she actually wants to read books instead of just eating them. Then it would also be kinda hard to hide "staring" at something/someone as she would have to turn her whole head into that direction.
Wait a second....plants and books seldom run...If she has a such highly developed visual recognition system, that is directed to the front...doesn't that mean she is a predator?
