Speechless

A Death Note Fanfic by Sjezza. In it, Light becomes mute after an accident with criminals on his 15th birthday. While it opened his eyes, Shiro is out for revenge. The strange shivers concerning those heart attacks aren't helping either.

It can be found here.

This fanfic provides examples of the following tropes:
"Ryuk was pretty much used to it by now. The kid had cracked and would often whisper to himself without realising it."
 * Artifact of Death: The Death Note, of course.
 * Asshole Victim: Shiro.
 * Better to Die Than Be Killed: Kira contemplates this when Light is attacked by Shiro
 * Crazy Jealous Guy: Kira towards Light. Subverted since he doesn't show this to anyone.
 * Face Framed in Shadow: Kira.
 * Genius Sweet Tooth: It's a Death Note fic. Of course this will be here.
 * Healing Factor:
 * I'll Kill You: Kira is now obsessed with killing L.
 * Laser Guided Amnesia: Light, in regards to his meeting Kira.
 * Life Energy: Apparently what the Death Note uses to kill people. Rather ironic.
 * Living Battery: Light unknowingly acts as this to the death note.
 * Mercy Kill:
 * Overprotective Dad: Soichiro. Can't really blame him since his job means he knows all too well what sort of nasty people are out there and his son lost her voice due to one of those nasties.
 * Sanity Slippage: Kira give indications at the beginning of being unstable but in later chapters, he's snapped.
 * Overprotective Dad: Soichiro. Can't really blame him since his job means he knows all too well what sort of nasty people are out there and his son lost her voice due to one of those nasties.
 * Sanity Slippage: Kira give indications at the beginning of being unstable but in later chapters, he's snapped.


 * Silent Snarker: Light shows shades of this.
 * Sufficiently Analyzed Magic: Played with. Little being known about the workings of the Death Note. There are two key points known by Shinigami play a key role in Light's ability while someone else is the owner. Ryuk reseached what was known because he was bored.
 * Supernatural Sensitivity: Light can sense when
 * The Speechless: Light, as a result of the incident that changed his views regarding criminals.
 * There Are No Therapists: Adverted. A psychologist shows up the first chapter although his profession isn't listed until the second. He also keeps in touch with Light.
 * Villainous BSOD/Villainous Breakdown: Kira.
 * Wham Line: Light nails L with one of these when he meets him for the second time,
