The neutrality of the Library is at stake as Librarians Irene and Kai find themselves smack in the midst of things. The Queen of the Southern Lands is forced to quickly find a suitable dragon to replace her deceased Minister and her challenge for the candidates has the potential to upset the balance the Library has so carefully crafted. Irene and Kai will have to risk everything if they are to save the Library. Will it be worth the cost?

Oh, my! THE LOST PLOT has catapulted The Invisible Library to my list of favorite series! While set in a very 1930s gangster-style world (a setting I normally avoid like the plague), THE LOST PLOT keeps readers on the edge of their seats as gangsters, mob bosses, prohibition, dragons, and even the fae all collide in one heck of a tale. Irene and Kai are caught between various factions as they try to resolve the sticky situation in a manner that doesn't compromise the Library, even if it means sacrificing their own lives.

I can't rave enough about Irene as a hero! I love her spunkiness, particularly in the face of mind-numbing odds. One of the things I liked best about THE LOST PLOT is that Irene is put in positions where her power as a Librarian isn't available to her and we get to see her ingenuity and intelligence in action. Her loyalty to the Library, as well as to her mentee Kai, is also admirable. And oh... who doesn't love Kai? I have to admit I missed seeing Vale, I hope we get to see more of him in future installments in the series.

THE LOST PLOT is the fourth book in The Invisible Library series and one that is best appreciated in the context of the series as a whole. The plot twist at the end has me quite anxious to see where Genevieve Cogman plans on taking this series and you can bet I'll be reading it as soon as it's available!
