His Mother's Son — Cai Emmons

To those who meet Jana Thomas, hers seems a perfect life, with a beautiful home, a successful career as an ER doctor, a loving husband, and a darling six-year-old son named Evan. But inside, Jana is crumbling. Evan's seemingly normal all-boy tendencies are escalating her motherly worry into something close to hysteria, threatening her job, her marriage, and even her relationship with her son.
The real source of Jana's disintegration is a past she has kept buried for sixteen years. When that past begins to bleed into the present, Jana is forced to plunge into the emotional whirlpool she left behind-with results that are shattering, profound, and wrenchingly moving.
Reminiscent of Sue Miller and Jane Hamilton, Cai Emmons's extraordinary first novel strikes a fine balance between keen psychological observation and page-turning momentum.
