Written in the 1970s, this book has sold many copies in numerous languages. The sketches of the trolls need no translation. Some are ugly and some are mean while others are almost cute.
Trolls, who generally prefer to leave their homes during night hours come in various kinds. There are trolls who live under bridges, some who live in water, others who inhabit the mountains, and yet another kind that prefers life in the forest. Some are entertaining, some just plain weird, and others who are scary. One never knows where they might lurk.
