Beneath the Christmas Stars by Tracey Alvarez

Wish upon a Christmas star tonight…
Karen Wallace’s festive spirit has gone A.W.O.L three days before Christmas. Her perfect solution? Take a road trip to spend the holidays with her friend’s family. Then a broken down car leaves Karen stranded at her friend’s brother’s house, along with his Grinch-like but kind-of-cute, roommate, Art. Short of Santa’s magic direct from the North Pole, nothing will make the next few days bearable. Not even Art’s stolen kisses beneath the Christmas stars.
Art Donnelly doesn’t believe in magic anymore-the Christmas kind especially. As a scientist working at one of New Zealand’s most picturesque star-gazing observatories, he believes that what you see is what you get. Planets, solar systems, and black holes are more reliable than joy, peace, and love. But love doesn’t play by the rules of the universe, and Karen might just change his perception of the Silly Season forever.
