Many years ago I read a book; I can't remember the name and I want to reread it. Can anyone help me out?
Settlers land on a planet and colonise it; they find this nasty creature that's a wee bit violent and start killing them all; later in the year, they discover that the creature was killing other smaller animals who later in the year turn into huge killing machines.
They then spend their time trying to survive from the new born creatures.
It was a great book but I can't remember the title.
This sort of theme was touched on repeatedly in a book published in 1991 by Janet Kagan called Mirabile. The book is a series of stories about the colonists on a new planet who often had to deal with obnoxious animals due to genetic engineering on the planet gone wrong. The colonists often didn't know which species were Terran gene-engineered monsters or Actual alien beasties, but trying to exterminate pests often lead to worse problems when it turned out the pests were restraining even worse species/pests.
