Bargain @ $2.99 for Canadians in the Kobo store as the Deal of the Day (Nov 23rd, should be good until 9 PM Pacific Time, when their servers switch over) from Doubleday Canada:
The Tudor Inheritance: A Novel of Tudor Rivals and the Secret of the Tower from popular historian-turned-novelist Alison Weir (
Wikipedia), about Exactly What It Says In The Title.
This is "on sale" for $4.99 from Google Play, so it looks like Kobo may have discounted it by another $2 just for today (seems to be matched at iTunes & Amazon Canada, though; the trick will be to see if it goes up later tonight), as they sometimes do for their Daily Deal (in my previous experience with these, the price will go back up immediately once the "day" is over). Also in my experience, Kobo's price listings start to fluctuate at 8 PM Pacific Time, but between then and 9 PM, you can still get a book at the sale price, even if when adding to cart you see the higher price, as long as it says the lower price you expect it to in the actual checkout confirmation page before you pay (take screenshots just in case, though).
England's Tower of London was the terrifying last stop for generations of English political prisoners. A Dangerous Inheritance weaves together the lives and fates of four of its youngest and most blameless: Lady Katherine Grey, Lady Jane's younger sister; Kate Plantagenet, an English princess who lived nearly a century before her; and Edward and Richard, the boy princes imprisoned by their ruthless uncle, Richard III, never to be heard from again. Across the years, these four young royals shared the same small rooms in their dark prison, as all four shared the unfortunate role of being perceived as threats to the reigning monarch.
Weaving together their lives and fates into a dark mystery of thwarted love and ruthless ambition, Alison Weir has written the most suspenseful, large-scale novel of her career.
