I am completely blocked and cannot write anything further! My FMC just got kidnapped and I don't know why!!!

To give you some context:Her estranged father is in a biker gang. She has had nearly no contact with him her entire life but after hearing he's out of jail, she and her friend decide to visit his bar as a way to get closure. Nothing really happens. Just about 20 minutes of catching up. Her dad's glad to see her and proud how she's grown up. That sort of thing. Nothing shady.

But I have her friend (they think it's the daughter) kidnapped.

I think I have it all orchestrated by a younger guy in the gang who wants to get back at the dad or start a war. But I'm not sure. The dad's loyalty is pretty strong to the gang (he just did time for them). He's not a high official member. The daughter's not a threat.She's kidnapped because of her dad. No back stories.

So, I have her kidnapped but no idea what to do now.

Why did they kidnap my FMC?!

Any help asap is appreciated!!! I really want to get back to writing this!!!

They guy who kidnapped her is her half-brother, furious that she dropped out of nowhere and got dad's attention and approval, while he tried to fill dad's shoes in the gang the whole time he was gone, but is being ignored/maligned for falling to the dad's level/otherwise left with daddy issues.

Good luck!

Okay, I'll bite. Here are some thoughts:

• Stories are built out of conflict. Unless the meeting between the dad and daughter is at the end of the novel or else is focused on character development and is lulling the reader a bit before dropping the next anvil, it probably shouldn't go quite as idealistically smooth as your blurb makes it sound (but this is editing advice, so disregard while in November!).
• Conflict between the younger guy and the girl's dad could be a useful misdirection for the reader; the dad's non-leadership role in the gang makes is unlikely that this is any kind of power play, which to me signifies that there is another motive at play. Could it be that the younger guy had a crush on your FMC while he had been in school (but she never noticed him or gave him the time of day) and this is his misguided attempt to (forcibly) win her over?
• Another twist: your FMC is mistaken for someone who just inherited a significant amount of money; or she is unaware that she just inherited a significant amount of money. And the kidnapping is for a ransom.
• Another thought: your FMC is somehow important to a rival gang that was responsible for the younger guy's friend getting killed or set up by police; the motive for the kidnapping is revenge.
