Poisoned Pen Press seems to be feeling their oats right now, and putting a few authors/series on sale that usually don't go on sale, and are pretty expensive when not on sale.
Painted Veil is the second in the historical Tito Amato series by Beverle Graves Myers. It's on sale for $1.99 in the US, and discountable at Kobo US. I luckily picked several of these up back in Fictionwise days, since I haven't seen any of these on sale in years. This is a really nice six-book series that I wish were longer.
