Obviously thrown together quickly with little editing. Bits are repeated several times, characters forget things they were told two paragraphs earlier, the dialogue is terrible and the plot only takes up about a third of the book, the rest of which has Tully wandering about eating meals and talking with people who have nothing to do with the plot. McManus evidently intended it to be a farewell to a series he's gotten tired writing, with passing mentions of various characters who have appeared in the books, but it just ends up being a mess.
