The Good Sister starts off slowly – to be perfectly honest, it starts out slowly for the first third of the book. However, if you hang on, the rest of the book will definitely be worth your attention.
Rose and Fern, fraternal twins, grew up with a sociopathic abuser of a mother. Fern, who clearly is autistic (most likely Aspberger’s) is protected both in her youth and in her adulthood, by Rose. Fern of course lives a fairly regimented life until she finds out that Rose cannot get pregnant. Fern decides she’ll show her love for her sister by having a baby for her. The narrative is provided from the point of view of Rose, via her journal, and Fern, via her simply living her life.
That’s the basic storyline, and it doesn’t really take off until Fern has to start varying her routine, given that her routine has not thus far allowed her to do things like go and dates and such. We also find out that Rose is not quite the doting and caring sister we think her to be based on the opening of the book.
There’s a lot to like in this: it’s a psychological thriller, without a doubt, has some good twists, and has one of the main characters afflicted with a condition without taking that character into some weird place, which happens all too often. The writing is good, and there are no major plot holes. If the front end was a tad speedier, I’d give it five stars, but it still is a solid four star read.
