The Heir is the debut novel for Grace Burrowes, and as debuts go, it's not bad. As other reviewers have pointed out though, her knowledge of Regency England is lacking. The Earl discovers a liking for muffins - the American variety - and cookies. Neither of which existed in England at that time. And forgive me my squeamishness, but to me, the hero using his chamber pot holds no place in a romance novel. Heroes - and heroines - don't go to the toilet in romances - or movies. It just doesn't happen. Every time we were treated to a description of him taking a piss, I cringed.
From a technical nit-picking perspective, the editing was also a bit hit and miss with a few words repeated or just downright incorrect - perhaps that only applies to the Kindle edition.
I stuck with it, even though the heroine's story took an age to actually get anywhere. There were flashes of excellent humour when the brothers were together and I had a liking for the Earl, but I found it difficult to like Anna, the heroine. Her hearing-impaired sister Morgan was a much more interesting character and The Heir tantalised with a possible romance developing between Morgan and the Earl's younger brother Valentine.
One aspect I thought Grace Burrowes handled very well, with great sensitivity, was the way the household and family gradually recovered from the death of their other 2 brothers. Her writing was spot on as the Earl came to realise how things had moved on, and how they were all starting to live again.
I think Grace Burrowes has potential as a writer, and I will certainly read her again.
