The story never ends when the book shuts

"So when do I get to use the badass, lightsaber-like ninja weapons?" Simon asked, grinning up at Isabelle who sat perched on a beam in the Institute attic. Since becoming a Shadowhunter, Simon had spent most of his hours training. It was difficult work, a lifestyle he still couldn't get his head around. The burn of the stele as the tip met his skin, the ability to use all sorts of runes to strengthen him; it would all take some getting used to. The highlight of this though was living with Isabelle. Since the secret of the Shadowhunter s existence had to hide from all mundanes, he had to leave his family, seeking refuge at the New York Institute where the Lightwoods took him under their wings. It pained him to part from his family, considering they had only recently been together again but he had told them he was away at University so he could still visit occasionally. His memories of life before being a Shadowhunter were vague but the warmth of his friends around him, the love in their eyes confirmed how much they must have meant to him. "When you can actually start listening to me and follow my instructions." Isabelle replied, flipping off the beam and landing soundless face-to-face with Simon. Plus, it s a seraph blade. You ve sat through enough weapons lessons to know that already She flicked her raven-black hair into his face as she swirled to exit the room. Simon, still dazed by the proximate closeness of Isabelle's face seconds ago, shook his head and reached for her hand. "Come on, I bet you never listened when you were learning. Probably too busy staring at the angel-like face of Jace for all I know." He muttered with no hint of harshness. Isabelle punched his arm lightly."You just called Jace angel like, that s something he'll love to hear you know maybe his head will grow slightly bigger than it already is." He put his arm around her waist, feeling the rise and fall of her breath. The perk of being a Shadowhunter is he finally felt he belonged somewhere and that is a feeling he would never tire of.
