There are blessedly few of these and only one truly bad book. I have had the very good fortune of reading some wonderful books this year, which can be read here.
And I mean bad in every way. The writing was cliched and repetitive. The characters were laughably two dimensional. In fact some barely had that many dimensions! The plot was nonsensical with more holes than a colander. The descriptions were pedestrian.
Ladies and gentlemen, the worst book I read this was Guillermo del Toro and Chuck Hogan’s The Strain.
Do not waste your time on it!
I wonder what it says that two of my least successful reads were co-written. I hope the both Messrs del Toro and Pratchett were minor contributors to these disappointing projects.
One more co-written book which was so bad I did give up on it was Dragons Of Autumn Twilight by Margaret Weis and Tracy Hickman. I’d picked it up – well downloaded it – as a trip down memory lane having warm memories of it from reading it as a kid. Alas, some things should not be revisited. Banal. Tedious. Formulaic.
A small part of my childhood died as I read it.
