Element of Surprise. Super Short Super Hero Instalove Romantasy, #6

Jem, once a respected geologist, now possesses the ability to manipulate the earth and conjure stone golems. Haunted by her past as an unwilling subject of the Aethor Institute's sinister experiments, she finds solace in the Protogenus organization, where she can channel her abilities into revolutionary gemstone research. Chris, a former firefighter who can control the earth's elements, faced rejection and discrimination after escaping the clutches of the Aethor Institute.
Determined to use his powers for good, he joins the compassionate team at the Gemini Institute, dedicated to safeguarding lives and providing sanctuary for the vulnerable. When fate intertwines their paths and the Gemini Institute sends Chris on a mission to confront Protogenus for their crimes against supernatural beings, Jem is prepared to defend her new company and her new friends. However, an unexpected force binds them together-a profound and undeniable connection that neither of them can resist.
The Aethor Institute had created them to be each other's perfect mate. Struggling to reconcile their loyalties, Jem and Chris must find common ground or risk losing their chance at happiness and eternal love.
