I got out of the habit while having young children. Also having a smart phone doesn't help as it's always there for 'easy' reading.

I think start with books that are well-written but not too taxing, so that you'll actually finish them and not give up. Then when you realise you are a reader again you can move on to weightier works. Or not! Nothing wrong with reading whatever you find enjoyable.

Right now, I highly recommend Big Little Lies by Liane Moriarty. It's very gripping and funny, while dealing with some serious issues.

I also enjoyed the Robert Galbraith (JK Rowling's pen name) detective novels. They have a breezy tone but keep you reading to the end.

If you want to start with thrillers these aren't too long and really interesting!

Misery - Stephen King
Mine - Robert R McCammon

I would suggest Maeve Binchy, a bit chick lit but some good undercurrents. Or re visit children's fiction, I loved rereading the 'Swallows and Amazons' series and 'Malory Towers' and 'St. Claire's'.

For thrillers and crime try The Shardlake series by CJ Sansom, or (not quite so well written but still fun) something by Gordon John Thomson.

A couple I've enjoyed recently are The North Water by Ian McGuire and The Light Between Oceans by M L Stedman.

Happy reading!

I think thrillers are quite good to help you get back into reading. I started off with books like Gone Girl and Apple Tree Yard. The 'page turning' element help.
I agree that smartphones don't help! They're too distracting and don't help with concentration levels.
