I'm so excited that we get to return to the world of the Kings with the next generation series: Ruthless Heirs. Ruthless Guardian brings in the new wave with the daughter of Stella and Luca; Isabella.

Tropes:
👑Bodyguard = forbidden 
👑V-Card Mafia Princess
👑Forced Proximity 
👑"Good Girl."
👑Grumpy x Sunshine
👑Possessive Obsessed MMC
👑Mafia World

Isabella is the oldest child of Luca and Stella, and even though she is the daughter, Luca has plans to have her be the next head of the family and run the family business. However, Isabella doesn't want that life, she wants to be a doctor and is working hard in her studies to reach her goal - even though she knows she will most likely have to follow in her father's footsteps.
During a night out with her cousins, Isabella's long-time bodyguard is shot and killed, which opens a new bodyguard spot. Enter the delicious, serious, sexy, strict, drool worthy, Raffaele. With a resume and a body she can't say "no" to, Isabella hires Raf for the open position. 

With school, Isabella has an opportunity to travel to Rome for the summer. The only way her overprotective father will approve the travel is with her new strict bodyguard to accompany her. However, with a troubled and secret past, Raf refuses to return to his Homeland... but being the Principessa that she is, Isabella is able to get him to agree to go with her with her own ways of persuasion. 

With the sexual tension already in place, it is only heightened traveling to Rome and being roomed together and having very close proximity. Raf knew from the beginning with the position that his attraction to Isabella should be reason enough to not take the job, but he just can't stay away. The tension between the two seriously is off the charts, and I'm surprised my Kindle didn't catch fire.

With drama, tension, a shoot out here and a shoot out there, secrets coming to light, the two just can't deny their feelings for each other and you just can't not cheer for them. 

I think Isabella was the perfect balance of a Mafia Princess. Yes, she wants her own life, but she also knows her expectations. She's attracted to Raf, even she knows that she shouldn't and really can't have him. But, she's also a strong female who knows what she wants and goes for it anyway. I applaud her. I thought I would have been annoyed with the spoiled Principessa, but no, she was so wholesome, sweet, and good. I just loved her. Then with Raf... *sigh* *drool* Sorry, brain is mush, and I have no words. He can tell me what to do anytime!

Highly recommend and can't wait to read the next books and how the rest of the cousins and Isabella's brother fair!
