Summer Lightning is the third Blandings Castle novel, in which we are first introducted to both the prized pig Empress of Blandings (at least her novel debut) and Lord Emsworth's brother, Galahad Threepwood. Lord Emsworth also has a new secretary, as well as two young relationships that seem to interfere with his time in the garden. Pigs are stolen, Baxter is efficient, and one of likes tea, and the other...does not. Robyn misses Freddie, but finds herself of a like mind to Lord Emsworth, and Scott wants her to talk a little more.
