[bookmarked]

I bought all 6 of the ones on sale. I was able to use these 3 on my Kindle 4 NT e-ink device, as well as the Cloud Reader. I wouldn't necessarily recommend reading them on an e-ink device, but it was possible.

• Attack of the Deranged Mutant Killer Monster Snow Goons: A Calvin and Hobbes Collection
  
• Homicidal Psycho Jungle Cat: A Calvin and Hobbes Collection (Calvin and Hobbes series Book 9)
  
• The Days Are Just Packed (Calvin and Hobbes series Book 8)

It would only allow my to use the other 3 on my Android tablet - no PC, no Cloud, no TouchPad.

• The Essential Calvin and Hobbes: A Calvin and Hobbes Treasury
  
• The Authoritative Calvin and Hobbes: A Calvin and Hobbes Treasury
  
• The Indispensable Calvin and Hobbes: A Calvin and Hobbes Treasury

I'll have to look into using the tools with my Kindle instead of with Kindle for PC.
