Trinity Rise Series book 1-3?

Book one.

How To Discover A Child's Secret.
A young boy with milky looking hair tugged on his mothers sleeves, desperate for the attention. The woman turned her head and bent down to the boy. The young boy looked at his mom with no reaction until he finally blurted out something.
'Mommy... why don't I have anyone other than you?' The boy asked his mother. Desperate for any sort of reply. The woman's eyes widen.

The woman could only stare dull at her son. The question spun around her head. 'M-mommy?" The boy asked for his mom. Getting worried. The woman's light hair covered her eyes. And the woman fell down. On the floor.
'Kyle.. you - you.. did have a sibling.' The woman managed to spit out.

Kyle looked at his ma. She got up from the grass and brushed the bits of grass off her amazing gown.
'But she was kidnapped. Ages ago..' His ma said. The boy looked at his ma with absolute shock.
'W-will we find h-her?' He asked. Hope filled his voice.
'We will..' The woman answered.

I woke up that morning. In the same orphanage clothes. My hair was messy and I started to brush my hair. Silky smooth.
'Morning.' I shouted for all the children slumbered to wake up. Like I always did. So the caretaker we call 'dad.' Doesn't have to.
The children got ready and raced around trying to cover up any sort of messes.

'Hey! No running!' A brunette called desperately for her siblings. The girl had finished getting ready and only had to tie her hair.
'Hey, Dalia.' I say morning to the brunette. I decided to exit the room into the halls.

'Oh. Trinity! Just the kid I was suspecting!' Father welcomed me with a warm smile. I smile back.
'Everyone's awake, pa. I'll create breakfast now.' I say and walk off to the kitchen. I started to cook as usual.

'Where's trinity?' Asked the brunette, Dalia.

'She's creating breakfast.' Pa explained to the kids. Everyone went 'Ohhhh!'
At that point I'd finish the eggs when I heard a huge scream.
'AHHHH!' The scream escaped someone's mouth. I added the last egg on the plate and checked to see what was happening.
There was Katie screaming her lungs out.

'Katie...' I look at her. Head titled. Confused of her sudden screaming. I took the tray full of food and place it down on the tables. No one ate yet. I walked over and bent down to help Katie.
'What happened?' I asked my voice became more serious. She gave me a huge fright.

'I- Saw- fall - no - help - help' She stuttered.
'Oh Katie I'm so sorry!' I hugged her. Everyone was confused

'What did she say?' Asked Dalia.
'She saw a child fall with no help. She screamed for help but no one came. So then she came here and found the child here.' I explain. Everyone's mouth dropped.

'Let's continue, okay?' Father tells us. I nod. The wind picked up outside and the trees leaves fell off. Showing autumn / fall.
'We are thankful for this food Trinity has made us.' Father tells us to repeat. I just say what I have made. Instead of trinity.

I began to dig in, scooping up the bacon and eating it. That's when a huge thump came.

—{{{{{{{{{ BLOOD WARNING. SKIP IF UNCOMFORTABLE}}}}}}}}—
I turn to see a pile of blood come from Katie's mouth. Everyone was frightened.
'K-Katie?' I ask looking at her confused. She let out an ear piercing scream which made me cover my ears
Blood dripped down her clothes, from her mouth.
'I-is that a knife?!' Asks Dalia seeing a knife next to her. The lights had only flicked for a second.
Father looked down. Shocked. 'I'll take her to the infirmary!' I volunteer and take her. I use my jacket for her mouth.

I place her gently down onto the bed,
'Katie!' I scream at her, making her snap out of the thoughts.
'What happened-' Katie asked, before she could finish. She fainted. I screamed as blood came out of her mouth. I throw my jacket over her and take a fresh one,
