New Book | Black Cake

I purchased "Black Cake" while on a recent trip for work because I forgot to grab a book from home when I left. And so far it's hard to put this one down. I'm still very early in the chapters but I am hoping the strained relationship between the brother and sister mends itself as they collectively seek answers during the extremely difficult time they are facing. I already have hope for the both of them. I'm also very interested to see how the story reveals some hidden family secrets and explains the significance with the title.
