One of our Thursdays is Missing (2011)
I usually don’t worry too much about spoilers here, but the reason I thoroughly enjoyed this latest Thursday Next-adventure would be one ginormous spoiler. I think it suffices to say that Fforde does something different (and rather cheeky) in this installment, and it really suits the series. So if you enjoyed the other TN-novels, hurry up and read this one. If you’re new to Jasper Fforde and his literary detective Thursday Next I recommend starting with the first volume, The Eyre Affaire.
