Lorelei Bell 
The Serial Killer Beside Me [EPUB ebook] 

After a girl’s body is found near the Mississippi, close to where Lainey lives, it sends a shockwave through town. Soon after, another death occurs, and it becomes clear that a serial killer is on the loose.
Lainey is facing trouble of her own in the form of a bicyclist, who nearly runs her down. When she begins getting odd phone calls from a man, Lainey wonders if the biker has something to do with the case.
When Lainey’s best friend Nadine is abducted, tensions rise and Lainey vows to rescue her friend and bring the killer to justice… even if it means she must put her own life at risk.
In the third book in Lorelei Bell’s ‚Lainey Quilholt Mysteries‘, the young sleuth comes face to face with her most dangerous foe to date.
