Happily Ever After: Part III & IV by Melanie Martins

PART THREE
After Margaret threatens her, Petra has no choice but to go to St. Moritz in the hopes of convincing Emma to terminate her affair with Yara once and for all.
But Yara has her claws deep into Emma and breaking them apart reveals to be much more difficult than Petra anticipated.
The only way out seems to be for her to find someone else for Emma to fall in love with, but it had to be someone perfect.
Someone just as successful and captivating as Yara.
But who?

PART FOUR
Back in Manhattan and reunited with her family, Petra soon realizes that her married life isn’t going to be as peaceful as she’d expected.
Having your best friend hanging out with a world-famous artist has its perks, but there are also some dangerous downsides––especially when you’re the mother to newborn twins.
Even worse, as she tries to navigate through it all, another member of the Van Dieren’s clan is now trying to reconnect at any cost in order to ask her a very peculiar favor.
Regardless of her current grudge against them, is Petra really ready to go right back into the lion’s pit?
