My title says it all. Sort of predictable alien slugs trying to take over the world. set in the future though not a lot of description given on that - you just figure it out eventually. Some interesting creative plot points and some predictable and/or slow points. Good narrator though does help.

Mild warning for women who like sci-fi: you're likely already used to bizarre and unrealistic depictions of women, however, this author has a puerile view of the female sex that can make you want to stop listening due to disgust. It is not possible to only blame the time in which this book was written...
