Being Mrs. Dracula

I got bored halfway into the book. Although it was interesting to see the life of this new family, it was also repetitive. This is essentially a story of a polygamous marriage where bonds and love between them is constantly challenged through the centuries. I didn't understand why Valeria and Ilona couldn't leave Transylvania but Vlad could. I would've liked more of an explanation of how Vlad became a vampire. How did he know what to do? He obviously is stronger than his brides, but why? Why was he able to turn into a bat but the others couldn't? At some point he mentions that he has a vampire army. What happened to them?
All in all this was well written with lots of potential but I found it boring and a bit lacking in substance. Enjoyed how it went full circle from where it began. The pace does pick up a bit towards the end and there is some action of sorts but it wasn't enough.
