In line with this, I'd also like to recommend 'The Gene'[0]. The author has informed me of new things (Even though I studied biochemistry during college) and also focused a lot on the ethical discussions relating to genetic modification. It also directly discusses CRISPR as it is quite new. I'd recommend all of Mukherjee's other books as well (Mainly Emperor of all Maladies).
