I'm working my way through reading all the Poirot books, I've really liked the ones I've picked up so far and currently I'm reading The Murder on the Links.
The best book I've read this year (out of two contenders) is Every Heart a Doorway by Seanan McGuire. I liked the setting and premise more than the plot - but I really liked the aspect of all these children coming from really stereotypical YA/Childrensbook fantasy worlds where you get a small synopsis of their adventures and can just imagine what a whole book featuring that would be like.
