Then, one cold, snowy, winter night, he finds a young-looking guy on his doorstep, shivering and frozen to the core.

Shielded by Lightning || Barry Allen
"She loved him in the quietest way-without expecting to be loved back." Barry Allen was struck by lightning, the night that changed his life forever. Little did Barry know he wouldn't be the one having a life changing experience. But before that, there was Danielle (Dani) Stone - the girl who lit up every hallway with shimmery eyelids, sarcasm in her smile, and a heart too big for her own good. He became a childhood best friend, although his was Iris. Their connection never really faded, even when time and trauma tried pulling it apart. Danielle attended Gotham University, majoring in Cognitive Science with a concentration in Emotion, Perception, and Neural Response and a minor in Experimental Physics. Now she's returning to Central City - stronger, older, maybe a little more broken than when she left. She didn't plan on coming a couple days before the Particle Accelerator (okay maybe she didn't plan). But she definitely didnt plan falling in love with Barry Allen all over again. As metahumans rise, Barry and Danielle find themselves drawn together by something more powerful than destiny: choice. Karaoke, battles that bruise souls, and quiet moments that scream everything they can't say outloud, they discover what it means to love in a world that's always running out of time. He's the lighting. She's the light. And maybe, just maybe, they'll save eachother. [SEASON ONE - THREE] [BARRY ALLEX X OC] DISCLAIMER: it will be following the flash series, i will not avoid barry's love for both iris and linda!! but if i do make more books of the flash sadly i will replace iris and put danielle in her position with barry :/. besides that i hope you enjoy this ;) [Highest ranking : #4 on the flash, #1 on iriswest, #1 barryallenxoc #3 barryallen #5 grantgustin #1 friendstolovers, oliverqueen #6 superpowers]

Beyond Good And Evil - Harrison Wells x Reader
After your brother, Barry Allen, got struck by lightning the night the particle accelerator exploded, you have the unique opportunity to enter the world-famous S.T.A.R. Labs and get to know their founder, Harrison Wells. Little do you know that this man is about to change your entire life... This is a fanfiction to the DC series "The Flash", season one. Since the intention of this story is to point out the relationship between the reader and the other characters, I took the liberty to just pick out relevant scenes and conversations and leave away the rest. For this reason, you will probably not understand parts of the plot if you haven't watched the series before. Moreover, I decided to write this fanfiction in English, which is not my mother tongue, so apologies for eventual grammar mistakes.Complete
