I tend to read a lot, mostly on paper and a bit on my Kindle, but if you think I only read Fantasy, you are wrong. Since my teens I have read a lot of Science Fiction as well, and a bit of everything else.
To avoid being directly inspired by other works of Fantasy during the actual writing process, I decided to mostly read Science Fiction while I wrote (but I did sneak in a couple of Fantasy books this year, as you can see some of the other reviews).
Sometimes I like to read books that I have read earlier. Reruns can also be fun. For instance, while I read Ringworld by Larry Niven (I can only recommend this) and its companion books. I had read three of the four earlier (I think it was the third or fourth time I read Ringworld, it’s as old as I am and its paper is quite yellow), but since a kind soul gave me one of the Fleet of Worlds books, and I discovered that the two series were connected and even had a shared ending in "Fate of worlds", I decided to buy and read both series from cover to cover.
As there are two series here, it can be hard to know which to read first, and I certainly did not. I love to be surprised by a story, so I make it a point not to read the back cover or a full review before I starts, I do look at the headlines, and quotes from reviews or ratings to see if it sounds like it might be a book for me though.
I wrongly guessed that the Ringworld books would go first, then the fleet of world books second, as that is the way they have been written chronologically speaking. But I decided to mix it up by reading first Ringworld and then Jumping to Fleet of Worlds. I then learned that the plot spans a very long time, and that the Fleet of Worlds book took place a long time before Ringworld. eventually I decided to jump back and forth between the series. It was ok that way, but It might have been smarter to read them in either the Chronological order or depending on the plots inherent timeline.
If you decide to buy the books then look at the timeline chart, on one of the first pages of the last book "Fate of Worlds", and then maybe you can decide on a better order that I picked.
