Barry Allen was never meant to be alone.
The night the particle accelerator exploded, lightning didn't just strike once-it struck twice. Barry Allen, destined to become the Flash, was chosen by the Speed Force to be the legend. But Rachel Lucas, a girl who by all accounts should have been hundreds of miles away, was chosen to be something else.
A guardian.
Brilliant, stubborn, and funny to a fault, Rachel never asked for powers. History should have remembered her as the world's finest private investigator, nothing more. But now she runs beside Barry-faster than him, faster than anyone expected-and every step threatens to unravel the future Eobard Thawne has spent centuries constructing.
The Speed Force calls her its angel. Thawne calls her an anomaly. And Rachel herself? She just wants to use her gift to help people, even if it means breaking bones-or physics.
But destiny has made her the one thing Thawne fears most:
the girl who can outrun him.

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]

A brilliant engineer and ex-firefighter, he works as a head engineer and maintenance worker of S.T.A.R. Labs. Alongside Dr. Harrison Wells, Cisco Ramon, Caitlin Snow, and Ronnie Raymond, the team are ready to reveal the Particle Accelerator to the world. However, when things started going south, the Accelerator starts to malfunction, and Y\N and Ronnie rush to see what's wrong with it. In the midst of the chaos, Y\N spots a civilian by the name of Dr. Martin Stein. When he goes to get him out of the room, the Accelerator exploded, leaving the fates of the three men unknown. After eight months pass, Barry Allen has taken up his role of the Scarlet Speedster. However, when Team Flash are faced with the return of Ronnie Raymond, they can't help but wonder...
