Take Eye of newt, and toe of frog, Wool of bat, and tongue of dog, Adder’s fork, and blind-worm’s sting, Lizard’s leg, and owlet’s wing,, stir well, blame it on Shakespeare, and claim you read it all, last year.
In no particular order:

One of the big books that ‘The Expanse’ TV series is based on. They broadcast one book per year, so I have to read two, to get ahead of the story arc, and stay ahead.

It’s been available for several years, so I thought that I would educate myself. It’s not Dr. Seuss level, but Hawking does a good job of making a complex theory comprehensible to non-mathematicians.

Possibly only ever published as a pulp fiction, not paperback, I didn’t have a copy of this, along with my other Hamilton books. I found this, perhaps inadvertently attached to another article that I was researching..

A men’s’ action/adventure book, good for passing time in retirement. This is the third in a series. The first was terrible. The second was so-so. The story arc is improving. If I hadn’t already bought this one, I might never have.

Mark Twain, making fun of Christians’ beliefs about heaven. I’ll post a book-review later.

Like John Grisham’s work, Robin Cook’s is also dense. I read Coma, and liked it, but this one took me a while to struggle through.

This is the second of the Expanse books that I read last year. The next TV series became available on December 18/19, but I’m saving it till summer.

Tom Clancy’s ghost keeps pumping these out, and I keep reading them.
Extraordinary Popular Delusions And The Madness of Crowds

I’ve already done a book-review on this one. Interesting enough, but too old to be relevant.

Fun but formulaic Science Fiction. The daughter of a University professor grows up with enhanced cognitive powers.
Galileo Goes to Jail, And Other Myths

Research into Christianity vs. Secularism.

more research into Christianity vs. Secularism. The author has more than 20 books about the New Testament. I just can’t believe that he points out all the mistakes and contradictions…. yet says that he still believes.

One of two I that I read, that are the last in this series. Magic in Atlanta. I’ve already started on another series by the same authors, Magic in Red Deer, Texas.

One well-known author butted into another’s series, and wrote two books. It took the first as much time and effort to edit them, and assure that they fit in the canon, as if he’d written them himself. The other title is Sinners, which I’ll read this year.

A collection of Jack Reacher short stories.

Dan Brown’s latest – unless he’s released another one while I was publishing this list.

This author likes to play with alternate timelines & realities.

It wasn’t as interesting as I’d hoped – but then, perhaps people named Smith just aren’t interesting.

A story about space marines. The blurb sounded good, but the book was Young Adult – nothing wrong, just nothing right.

A book about how the original Star Trek was real…. or was it??!

The last in this sword and werewolves series – unless the rabid fans convince the author couple to write another. They are quite prolific, with four concurrent series, and a couple of stand-alones.

Not “Great Literature,” but a great time passer.

I’m reading these faster than Lee Child can write them. I will regret when the series ends. There are still two more ahead of me.

Science Fiction and time travel from a woman’s point of view. More suspense than action, but interesting.

I started this in Dec. but the need to read and return that next big Expanse book to the library in Jan. means that I’m just finishing it now.

Yet more Christians vs. Atheists research. Christian Apologists can be so irritating – unintentionally amusing and interesting – but irritating.
Even if you don’t have the time/energy to list all the books you read last year, do you have any specials that you’d like to mention?
