I have read two novels of this series, both in kiss and desire they never mentioned chase's kids meeting his side of the family. The only interaction I have seen is in kiss me liar that too with younwu's kids and josh's kids.
I don't know where people are getting this information either but from what I know Chase has gone no contact with his parents and siblings and all for right reasons.
Nathaniel's story was finished two months ago, the one which is curretnly running is Bliss's. But she will certainly revise Nathaniels story and it will get extras.
Nathaniel's happens around the same time as KMIYC. Desire is 5-6 years later, and it seemd to me that the phone contact was something that happened more recently.

So I keep seeing on the novel updates forum and Reddit that Ashley and koi met Pete but it’s not in kiss me if you can novel?
Where are people getting this information from?
