I always expect a series to have some highs and lows, and unfortunately, Teckla took a dive after the first two installments. I believe another reviewer noted that this was written while he was having marital issues; maybe not, but that might explain this, especially given the plot. Teckla takes place shortly after Jhereg, but unlike the fun mystery thriller motif of the first two in the series, this revolves around a failing relationship and the limits of idealism if you will.
Vald's relationship to his wife Cawti Brust presented as given in the first book; in the second, we learned how he met her (she killed him). Well, when Vald and Cawti were both revived, they quickly fell in love (at bit gag worthy, but not beyond the call). What drives Teckla are the new-found passion within Cawti for social justice and revolution. How did Vald not know about this aspect of Cawti? Did it just develop all of a sudden, or did she always have the drive and somehow it got activated? All in all, pretty dodgy to me. In any case, Cawti starts hanging around some revolutionaries located in the human quarter of the city comprised of mainly humans, but with some Teckla mixed in. Teckla comprise a major house (one of 17) of the Dragaera, but it seems most of their members are serfs in the countryside.
Well, Cawti and her new friends are planning a revolution to end economic and social oppression in the Empire and Vald knows this will get ugly. A big Jhereg boss rules the underground in the human quarter and tolerated the revolutionaries as long as they do not impact his 'business'. Once one of the revolutionaries gets offed (assassinated) by the Jhereg boss as a 'message' (yes, they did start to impact business), well, the ugly starts. The ugliness drives Vald and Cawti apart, as Cawti, like a good little revolutionary, digs in after the assassination, while Vald wants her out for her own safety. The only real mystery here is how the clash will eventually end.
While I have much sympathy for revolution, especially when the poor and down-trodden rise up to overthrow the oppressors, this felt rather ham handed to be sure. We have our passionate speakers of the movement and Cawti aligned against the hard practicality of Vald. In some ways, this installment gives us a different side to Vald, one torn between his 'street' ethics and the love for his wife and her ideals, but it just felt canned to me. Yes, the prose continues to be excellent and witty at times, but this was a downer for sure, unlike the fun, lighthearted first two installments. Workers of the World Unite! 2.5 radical stars, rounding up!
