The International Billionaires series collects fifteen Harlequin Presents novels featuring ultra-wealthy heroes from across the globe. A large portion of the series is built around the Di Sione family, eight siblings sent by their dying grandfather to recover priceless lost heirlooms. Each sibling’s quest leads to a romance, and the family storyline carries through from To Blackmail a Di Sione to The Last Di Sione Claims His Prize.
Outside the Di Sione arc, the series includes standalone titles with Greek tycoons, Italian counts, French businessmen, and Argentine billionaires. The books were published between 2009 and 2022, with the Di Sione books concentrated in 2016-2017. Each novel works on its own, though readers who follow the Di Sione sequence will get the most from the overarching family plot.
