An omnibus of the first three books in Sara Rosett’s High Society Lady Detective series is on sale for $0.99/£0.99 at Kindle US/UK right now. The titles are: Murder at Archly Manor, Murder at Blackburn Hall, and The Egyptian Antiquities Murder.
I’ve read a number of books in Rosett’s Ellie Avery/Mom Zone cozy series, and liked all of the ones I read. But I haven’t read any of the books in this series. Still, at this price for three of the four books in the series, I’ll probably give the series a try.
