It's not that bad, so I guess I can share it with you. +++ALERT SPOILERS+++
Isaac's dad, an Omega who was happily married with Isaac's mom, got tricked by his military colleague (who was a dominant alpha). That jerk raped him and marked him to make him his exclusive omega. The dad had no other choice than divorcing the mother and marrying that guy. Isaac never knew about that story because his dad wanted to protect him. The main villain in this story is actually that stepfather. He took Isaac under his wing and raised him almost as his son (thinking he was a Beta). He made him train hard to join the marine forces. But when Isaac's dad dies and other shady shit happen in the military, Isaac starts doubting the sincerity of the stepfather. They end up being enemies and that's why Isaac ran away and is now hiding the truth about him and his family. He wants to protect Benjamin and his mom from that powerful jerk. But the stepfather will find him and he will also know about Benjamin... it will be war between them but this time, Felix will be around to help out Isaac and his precious baby :))

Someone shared a Facebook link here in the comments. It was a while ago so I no longer have it, unfortunately. The book was actually in Spanish so you'll have to auto-translate to English using Google Chrome while opening the pages. The automatic translation is not very smooth but you'll get what's going on. If you want to find the link, go check out the comments many pages back. I think it was like 2 months ago like in September or something.
I can sense a sad backstory about the dad coming up as soon as I read the words "he was an omega". Bet my ass he went through something too. I've read way too many omegaverse and tragedy,i just KNOW it. Something bad's gonna be mentioned. Dammit. I hope i'm wrong
