The plot summary and the audiobook cover kept me away for a long time - I thought it would be just a version of "not like other girls" with tired puns. I'm so happy I pulled the trigger on this one night in the despair that finishing a book series and having to choose the next listen caused. Gideon the Ninth is gloriously all over the place and hilarious all the way. Harrow the Ninth is still hilarious but also even more scatterbrained. In a sense you get more for the price of one title, since listening them several times won't be an issue, cause I'm sure I missed a lot. 

Upped the rating from 4,5 to 5 just to add it to my 5 star reads i.e. favorites atm, in lack of a better way.
