The Double Effect — C.M. Okonkwo

Visiting Abuja for the weekend, Amina sees and falls for celebrity singer, Chuck-D. But there’s only one problem: she turned him down in high school fifteen years ago. Now in order to make him fall in love with her again, she and her reluctant best friend, Stanley, go on a time travel adventure to the past. But something goes wrong along the way, and Amina finds herself in an entirely different world without Stanley. She must evade those after her in the new world, find a missing person, retrieve a golden key, and race against time or she would be forever trapped in it.
