Victoria Greene would rather spend her time with machines than the high society she comes into contact with in London. She’s happy with her gears and cogs, even if that means she will end up a spinster.

When her father gets the funding for a trip to the Amazon to search for a mythical jewel, she jumps on the chance to come aboard as the Master Tinker. She expected to work on the massive boilers for the airship and to tinker with her mechanical creatures. She never expected the men suddenly thrown into her life making it even more interesting. The inventor, the cowboy, the scholar, and the dreamer are all intrigued by the woman who comes with grease on her face.

But something sinister is amiss aboard the airship and she’s determined to get to the bottom of it. Victoria’s suspicion rises the closer they get to Brazil and she must figure out the nefarious plans before it’s too late.

Can Victoria protect them all against the dangers, from onboard and the rainforest alike? Can such an eclectic team work together and find the Temple of the Rising Sun?
