Key Out Of Time★★★★☆
Andre Norton Lost in time, lost in space, out of their depth, a handful of humans are caught in the middle of a four-way power struggle on the high seas of an alien world.
Night Watch (Discworld)★★★★★
Terry Pratchett Time travel, barricades and a mix of humor and darkness in a rebellion with good cops, bad cops and time monks.
Star Trek: Discovery - Season 2★★★☆☆The stand-alone episodes are good, and the Burnham/Spock family dynamics, but the main arc gets really frustrating in the second half.
Star Trek: Picard - Season Two★★★☆☆Hard to pin down, with a weird start, then a few good time travel episodes, before throwing in not just the kitchen sink but everything in the sink.
The Time Machine★★★★☆
H.G. Wells A bit dry, but it draws you in, and if the plot is simple, it's enough to wrap around some thought-provoking speculation about the future of humanity - and a critique of industrial society.
The Time Traders★★★★☆
Andre Norton A fun time-travel spy thriller through the bronze age that's very rooted in the cold war.
