Cheated on by her fiancé weeks before their wedding, Sara, vowed to never love again. Men could not be trusted, especially with a woman's heart. She had made the mistake once, and that was more than enough for her. Never again would she make the same mistake to give her heart to another.But her resolve began to waver when she came across her new boss, Alexander Legend, a man whose reputation in his expertise and ruthlessness in business preceded him. Respected and feared by many, but to Sara, he was an annoying pest she wished she never met. Too persisted for her liking yet, she finds herself falling, slowly melting in his presence. Getting used to his stolen kisses and hugs and sometimes anticipating them.°°°°°Excerpts“You will fall for me, Sara. One day, I'll have your heart too,” Alex drawled. His voice had a seductive allure that had her heart racing. The fact that his hand was leisurely resting around her waist didn't help her either.“Try as much as you want to,” despite her body begging for his touch, Sara was determined to reject him today and any other day. She couldn't make the same mistake again. “You won't succeed in your seduction. NOT NOW. NOT EVER.”Alex smirked, kissed behind her ear and her body trembled, much to his satisfaction. That was all he needed to keep purising the stubborn woman in his arms right now. “We shall see, Miss Ambrose,” he cooed and then released her. He returned to his seat and asked in a professional tone. “What is my schedule for today?”

Shen Yu's world is facing the apocalypse. With the help of his Gray Mist Space, he could do good things such as saving lives to gain more gray mist and use it to do everything he wants to do. And what's more, no one but him can survive in the Space. However, this time, two figures walk out of the Space, and when they spin around, Shen Yu is shocked, because the two figures are all him from different worlds.“Your world is facing an apocalypse too?”“Indeed.”

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

Gustav born into an age where bloodline determines everything, struggles to fit with a useless bloodline.
His bloodline only grants him the ability to change his hair color, destroying his hopes and dreams for a great future.
His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!

Follow Gustav on his interesting journey filled with unprecedented adventures, danger and death, maybe?
