Dying To Remember by Sara K. Parker

Her missing memories could expose a killer...

After a gunshot wound to the head, Ella Camden turns to the only man she knows will believe she's being targeted, ex–love and security expert Roman DeHart. Trouble is, amnesia keeps her from remembering why someone might be after her. Roman let her go once. This time he'll do whatever it takes to make sure she stays alive – and his – forever.
