The Beginning of Always — Marie Cole

On the college campus of Aquanis the co-eds have one secret they've all been hiding - they all share blood with the unborn. They are all demigods.
For the mortal daughter of Cupid, Claire, this spells trouble; for her father's wife is eternally jealous and will stop at nothing to make sure that Claire's last breath comes sooner rather than later. Claire will soon discover that only one thing can save her, the one thing she helps others find, but has found to be elusive for herself - love.
