Morgen wollten wir zum Start unseres Hanser Taschenbuchs eine Party schmeißen. Als der Kulturstaatsminister die Verleihung des Deutschen Buchhandlungspreises absagte, haben wir den Charakter des Festes verändert & alle 118 Preisträger eingeladen, um sie zu feiern. Dies ist das neue Motto des Abends.

"It was the best of times, it was the worst of times." 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. #BookSky 💙📚 #TheStoryGraph

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.
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 Ausländer. All Woman, all good.

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 😜 #StoryGraph #Booksky 📚💙

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! 📚💙 #StoryGraph #Booksky

Linke Haltungen gleichsetzen mit psychischer Erkrankung. Das ist nicht nur für einen möglichen Kanzler eine völlig disqualifizierende Aussage, das ist rechtsextreme Rhetorik, auf dem Rücken erkrankter Menschen. Er ist gefährlich - ohne Übertreibung. Bitter, wenn er doch Kanzler werden sollte.

Heute hat die Union mit den Stimmen der AfD einen Antrag durch den #Bundestag gebracht. Das ist ungeheuerlich und eine Zäsur für unser Land. Für uns ist klar: Es darf keine Zusammenarbeit mit Rechtsextremen im Deutschen Bundestag geben.
Auf dem Bild ist das Abstimmungsergebnis der heutigen namentlichen Abstimmung im Bundestag zum Thema Migration zu sehen. In der Grafik kann man erkennen, dass FDP, Union und AfD gemeinsam für den Antrag gestimmt haben, alle anderen Fraktionen dagegen. Die BSW hat sich enthalten, einzelne Abgeordnete von FDP haben sich ebenfalls enthalten, ein Unionsabgeordneter hat mit Nein gestimmt. Darüber steht als Überschrift: „Gemeinsame Mehrheit: CDU/CSU stimmt bei Migrationsantrag mit AfD.“
