Full review at Smart Bitches, Trashy Books 
 The first full novel in Shupe's Knickerbocker series, Magnate is about the Gilded Age in New York, a man who went from Five Points childhood to owning basically half of New York City, and a woman who wants to start an investment firm. It's also one of those situations where the hero is a huge asshole, and the heroine only goes about halfway to call him out on it. 
 There's a couple things I really liked. First, Elizabeth and her determination to start an investment firm so she can play the stock market is based on a real thing that happened (Shupe talks about this in an author's note, THANK YOU) when Cornelius Vanderbilt backed two women, Victoria Woodhull and Tennessee Clafin, which allowed them to open their own firm, which was targeted towards women and helped a lot of women move towards financial independence. Elizabeth even calls this out when she's standing up against the haters (of course she has haters, omg a woman in BUSINESS heaven forfend): "If any of you want to increase your pin money, call me." So that's awesome. She's smart and is able to use her connections and access to women's spaces to make good trading decisions - including some that no one else has ever thought to make. 
 The main weakness is Emmett. He's almost a classical old school alphole: bad childhood, finds intimidating people and beating the shit out of them to be a reasonable conflict resolution method (to the point that his valet get miffed when he gets blood on his waistcoat AGAIN). One of the events that ensues during the story occurs when a former suitor of Elizabeth's doesn't really understand that, "No, I don't want to bang you" means "No, I don't want to bang you." Emmett takes this very, very badly, and even when Elizabeth is like, "No, seriously, I'm not running off with this asshole" he gets very possessive. And I can work with that, if there's a Come To Jesus moment where the hero grows and learns that this is not acceptable behavior. In this case, he apologizes, and she forgives him, but I'm not totally sure that she thought he was a hero behaving badly. TL;DR: NEEDS MORE GROVEL.
