In which book is caroline preganet?

In Nightfall (book 5) it's revealed that she's pregnant with Tyler Smallwood's unborn twins so I guess it was between book 4 "Dark Reunion" and sách 5 "Nightfall"....

in the end of the 5th book, she was whining that she needed a husband hoặc a fiancee. cause tyler skipped out on her. then she đã đưa ý kiến that matt raped her in the 7th. she wasnt mentioned in the 8th and 9th, so we don't know if she's had her "puppies" yet
