My science fiction/alternate history collection "Exchange Sampler and Companion" is free for one more day. Here's the blurb:
Safe in suburbia?
Not when town-sized chunks of our reality swap places with a wild, untamed alternate universe.
• A freaky smart bear escapes into our reality, changing it forever.
• An alternate reality with no people, no bureaucrats, no taxes. But freedom has its price.
• Terrorists plot to grab a potent bio-weapon.
