Calculated (Calculated #1)

Everyone claims teen prodigy Jo Rivers was born lucky, but Jo deems her gift a curse.

When she is betrayed by someone she loves, kidnapped by the world’s most wanted smuggler, and forced to use her near supernatural math ability to shore up a criminal empire, Jo's knows her destiny is sealed because in her world of numbers, there’s no such thing as coincidence.

But when fellow captive and unlikely sage, Red, teaches Jo to harness her true potential, she starts to believe she can do more than just escape. After Red reveals a secret about her enemies, he makes her vow to right his wrongs. But Jo has a vow of her own. With help from a bitter billionaire and his off-limits son, Jo rises into a new role, ready to take down those who ruined her--until a mathematical error comes back to haunt her with a threat much more dangerous than the criminals on the loose.

To beat the odds, Jo must decide who she really is and if risking everything is worth it. After all, history is not made—it’s calculated.
