The Dark Is Rising - 1. Midwinter Eve - BBC Sounds This night will be bad. Tomorrow will be beyond all imagining

A reminder that there is a bloody brilliant adaptation of "The Dark is Rising", done by people who love the books, on the BBC.

I met my reading goal of 40 books this year in November. I did wonder if I could read two Agatha Christie novels that month, but it was fabulous. No regrets.

I liked from recent reads:
* Tech: Marianne Belotti: Kill it with fire.
* Memoir: Jacinda Ardern: A different kind of power
* Sci-fi: Ann Leckie: Ancillary Justice
* Contemporary: Celeste Ng: Everything I never told you.

I'm also slowly reading myself through Agatha Christie's works 😁

Some statistics on books read in September, provided by Storygraph. 4 books read, all fiction, highest rated was Agatha Christie: Peril at End House. Also shown: Nettle and Bone by Kingfisher and poems by Rose AuslΓ€nder. All Woman, all good.

Regular reading is doing me good. Always cheerish Agatha Christie, and found a nice fantasy with kingfishers Nettle and Bone. Also finished another bike with poems - which I read in breaks during my volunteering gig.

Storygraph visuals on books read in August. 5 books with an average rating of 4.45. 60% print, 40% digital, one non fiction. Pictured books are "Die Wand" by Marlen Haushofer, "Maus" by Art Spiegelman and "Everything I never told you" by Celeste Ng.

August was a great reading month, all books were 4 stars or more. I really enjoyed how the reflective voice of Marlen Haushofers "Die Wand" resonates, even though it took ages to get through the book!

In July I started to track my pages read in a bit more detail, and just essentially read more overall (deleted Instagram from my phone πŸ˜‰). Finally finished @annleckie.com 's "Ancillary Justice" which is just so so good. Mind-blowing, highly recommend.

Only one book in June, a sequel, Caroline Wahl, WindstΓ€rke 17. Too much going on, hoping for a better reading month in July!

StoryGraph wrap up of books read in May. Only two this time, not highly rated, all digital.

Two surprise reads - didn't quite enjoy "Yellowface" as much as reviews suggested, and enjoyed "22 Bahnen" more than I thought I would.

Also a bit disrupted reading, as I've started to lend ebooks from my public library, so switched books whenever something got available 😜

Several graphics generated from the app "The Storygraph" show my reading history in April. Two fiction, one non-fiction books, with the non fiction book, "Kill it with fire" by Marianne Bellotti being rated highest with 5.0.

Not as many books, not as many pages as in the previous months, but all very enjoyable. Marianne Bellottis book "Kill it with fire" about managing aging computer systems was an absolute highlight. πŸ’™πŸ“š

A visual from the storygraph app showing an overview of books read in March. 4 books with an average of 4.13 rating, a total of 1161 pages with an average time to finish of 5 days. Highest rated book was Agatha Christie: ABC murders.

March felt like a slower reading month. Lots of changes happening to keep me occupied elsewhere. I was happy whenever I could squeeze in books. Again, Agatha Christie is such a staple for me, glad she wrote enough to keep me company for years to come! πŸ“šπŸ’™
