Query: A depressing series'-ender

Sarah Ash's Tears of Artamon series, which concludes dismally with `Children of the Serpent Gate' (Bantam Spectra, $23, 516 pages). `Children of the Serpent Gate' echoes the depression of `Prisoner of the Iron Tower', and what redemption comes arrives not only very late, but almost completely unbelievably. If you've started this series, the finish isn't really worth the time and energy; if you haven't, don't bother.
