FREE: Unexplained!

The listing, Unexplained! has ended.

There's a lot of strange stuff going on out there in the world, and it's worthy not only of our curiosity but also of careful investigation. And Clark has been doing that kind of investigation of paranormal claims for nearly three decades. He's a board member of the Center for UFO studies and the former editor of Fate magazine.
Unexplained! is arranged in six sections:
Cosmic Enigmas - lunar anomalies, the Tunguska event, and missing planets.
Shapes in the Sky - mysterious airships, Area 51, alien abductions, and UFOs.
Strange Showers - anomalous rain and other strange falls.
Earth Mysteries - ball lightning, crop circles, earth lights, and teleportation.
Cryptozoo - lake monsters, living dinosaurs, and other mysterious creatures.
Out of Place - Animals found where they shouldn't be.
Other Incredible Entities - Bigfoot, chupacabras, thunderbirds, and Men in Black.
Things That Are Not - Bermuda Triangle, Jersey Devil, and Noah's Ark.

There's a lot of good information here.
Each topic is presented with as much background as Clark could gather, and he often comments on how reliable the information is, how likely the incidents are to be true, and possible alternate explanations. The most telling chapter, perhaps, is "Things That Are Not" in which Clark exposes several stories, encounters, or phenomena as being hoaxes - or at least not having sufficient evidence or believability to be considered truly unexplained.
This kind of book is precisely what is needed in helping us think about the paranormal. Considering the quantity and variety of bizarre episodes that people report seeing or experiencing, it's clear that there's still much we don't know about this existence or how things really might work. Perhaps science will explain some or all of them eventually. And perhaps some will never have a satisfactory explanation.
