Hidden Pieces by Heather Gudenkauf

This is an excellent novel by Heather and just like "The Girl on the Train" by Paula Hawkins, I was immediately hooked even at the first chapter. Unlike usual murder mysteries, it did not start with a macabre tone. It began with a literary style normally associated with novels that had no murder-induced theme. Then it gradually builds up tension with the ultimate shock of the victim as she is confronted by her assailant.

The story is about Sarah and her husband , Jack, who goes back to Penny Gate because of his aunt's accident. Jack's aunt and uncle adopted Jack and his sister after their parent's untimely accident. Sarah , however, senses Jack's reluctance to go back even though it was evident that he dearly loved his adoptive parents. She eventually discovers that stories Jack told her were not entirely true. His aunt subsequently dies and they were not allowed to leave by the authorities due to  the suspicious nature of her death. Alarmed, Sarah decides to do her own investigation and unearths a throng of unfavorable details about her husband's family starting from his parent's death 30 years ago to his aunt's eventual demise.

A real edge of your seat thriller!
