Jewels of Bangkok — Megan Derr

Not so long ago, Elton had it all. A loving family, a jewelry business he helped his father run, and the esteemed position of Jeweler Troisieme to Mars. But the revelation of deep betrayals by his father tore his life and his family apart, culminating in a tragedy that forever ruined any chance of happiness for Elton and his sister, Lana. Parents dead, abandoned by friends, and their reputations ruined, Elton and Lana accept the offer of a new life on a planet far away from Mars.

Before settling into their new lives, however, Elton and Lana decide to stop on Bangkok, the notorious 'star of pleasures.' In the place where all dreams come true, all they want is to learn how to be happy again. But everything goes awry when Elton's unmatched skills with gems allows him to spot a fake necklace in a museum, a discovery that leads him straight to the legendary Jewels of Bangkok.
