Alaskan Royal Family, book 2: The Royal Pain
MaryJanice Davidson2005

Marine biologist Dr. Shel ("Never Sheldon") Rivers has a problem. Some princess expects him to wait on her, hand and dimpled foot. His boss is taken with the royal redhead--brunette, whatever, it's not like he keeps track of that stuff--and nobody realizes that he just wants to be left alone in his lab. All alone. All the time. Weekends, holidays. . .it's all good.

Now here's Miss Royalpants, insisting that he escort her around the marine institute, explain what he's doing, kiss her until her toes curl. . .no, wait, that was his idea. She's not even apologetic about being born into a royal family! Says it's his problem to overcome, not hers. Which leaves him with one option: to kiss her again. And again. And. . .

So she's nothing like he expected. In fact, Dr. Rivers can see that this fantastic, exasperating woman has problems no princess should ever have to deal with. And he has an idea to help her get some much-needed sleep. Of course, it involves getting very, very tired beforehand, but if she's up to it, then so is he. . .
