Every great author has to begin somewhere -- and with Patricia Briggs, it started with "Masques." Briggs' first novel is pretty obviously a first novel, since she hadn't yet gotten a solid grip on her pacing and her characterization, but there are flickers of brilliance in her shapeshifting heroine and vivid writing.
Aralorn is a shapeshifting spy who gets sent on some various dangerous missions with her friend Wolf, even to spy on the lethal Geoffrey ae'Magi (who uses magic to make people adore him... kind of like a politician). When the crown prince Myr is accused of murdering one of his guards, she knows that the ae'Magi has somehow framed Myr -- and she and Wolf quickly join a small, ragtag rebellion that Myr is forming.
But Aralorn soon discovers that Wolf has some horrendous secrets in his past, some of which involve the ae'Magi and his bloody magic. With zombielike Uriah and a dragon waiting outside Myr's caves -- and the ae'Magi intent on capturing some of their party -- Aralorn and Wolf must find a way to defeat the magician before he gains control of the whole country.
When reading "Masques," it's pretty obvious that this was a very early Briggs work -- the narrative is rather choppy, the worldbuilding is fuzzy (what are these countries again?), and everything bounces from crisis to crisis at a breakneck pace. It's definitely not a bad novel, but it has all the earmarks of an early work, written before the author's rough edges had been rubbed off.
But there are hints of Briggs' future brilliance in the story -- her prose is vivid and colorful ("led by a small, grey fox with ageless, sea-green eyes"), and it has moments of dry humor ("Nothing's going to get us but ghosts and vampires and other nice things that feed on stupid people who ride in the woods after dark"). And she evokes some feelings of pure horror, such as when Aralorn sees an old buddy turned into one of the Uriah.
And the storyline slows down and becomes smoother in the book's second half, as Briggs works out various storylines (the ae'Magi's master plan) and weaves together the various subplots.
There's also a nice romantic subplot for Aralorn and Wolf, both of whom are oddities -- she's a young shapeshifting spy with a lot of guts and kindness, and he's a cynical, scarred magician with some nasty ties to the ae'Magi. There are also some nice supporting characters such as the magic-immune Myr, the dignified dragon, and a spattering of others.
"Masques" is a pretty immature piece of work, compared to Patricia Briggs' later fantasy books. But it's still an entertaining, action-packed little novel with a likable heroine.
