Shacking Up by Abby Knox

Sam may have a ranch to run, but he’s not one to shirk his civic duties when he receives a jury summons in the mail. Fate, however, seems to be summoning him to the jury pool for entirely different reasons when a fellow juror half his age buddies up to him and refuses to leave him alone.
Nobody has ever stuck up for Wren before, who’s been on her own since she was a teen. When the grouchy rancher, Sam, acts on his protective instincts on her behalf, Wren is sure beyond a reasonable doubt that he’s meant to be hers for life.
