Have enjoyed reading the "Awaken Online" series by Travis Bagwell. It's sci fi and the premise is a new, immersive virtual reality game is launched called AO. Story is told from the perspective of the villain, which is new and interesting. It reminds me of "Ready Player One," although the characters are more interesting and there isn't a derth of pop culture references. It's available on the Kindle pretty cheap, and there are about 6 or so books now. It's one of those universes with endless possibilities.
Also picked up the Tripods Trilogy by John Christopher. It's a bit dated (I think it came out in the late 60's), and is told in the first person, which I'm not crazy about personally. It's kind of a combination of "War of the Worlds" with a cross country journey thrown in a la "Lord of the Rings," but without the fantasy element. It's a quick read, probably more for kids than adults. I remember seeing the comics in "Boy's Life" magazine when I was a kid in the 1980's.
Last one I gave up on was "The Company of the Dead" by David Kowalski. Premise was very interesting - set in an alternate future whereby the US lost WWI and the south seceded again, confederate separatists uncover a time machine and a chance to change history by boarding the Titanic. Unfortunately, the storytelling falls flat - there are way too many characters and the author parcels out the backstory as small anecdotes here and there, which is confusing. And the narrative is constantly shifting between time periods and flashbacks, which adds to the disconnected nature. After a couple hundred pages (out of 751), I finally moved on.
My wife wants me to read "The boys in the boat," by Daniel James Brown, which is on my to do list.
