I came to know about it as Kobo Cloud Reader from many websites like these..

Yes it was a mistake on my part that I didn't check Kobo website where they are calling it Kobo instant reader..Any way I send a mail explaining that what I meant was Kobo instant reader rather than Kindle cloud reader. Expecting response from them..
The book I purchased was Martin H Greenberg's anthology "End of the World"..All my other books in my library I am able to access..
