A promise too big to be defined by mere words.

He opened his mouth, and I put one finger over my lips in the universal sign for “shhhh.”

Tod rolled his eyes. He didn’t need to be reminded to make sure the living couldn’t hear him—one of the handier perks of our undead state. In fact, he often had to be reminded to let others see and hear him. In the two-plus years since his death, most normal human functions had fallen out of habit, and he’d once told me he wasn’t sure his heart ever beat when I wasn’t there to feel it.

I’d promptly melted into a puddle of Kaylee-goo.

My fingers curled around a handful of his shirt when he kissed me, and I stood on my toes to give him more of me. To taste more of him. “Mmm...” I murmured when his lips trailed from my mouth over my chin, then down my neck. “I missed that.”

“It’s only been a few hours,” he whispered, though no one else could hear us. “Shouldn’t eternity make us more patient?”

“It’s having the opposite effect. Knowing we should have forever makes me want a little bit of forever right now...” I pulled him back up, and my lips met his again. His hands trailed slowly up my sides, and I let the feel of him chase away the anger and sadness I’d been fighting for most of the day. For most of the past two weeks, in fact. Tod felt good. Tod always felt good, even when the rest of my world was falling apart.

“Oh!” He pulled away from me and reached into his pocket, then held up a small plastic vial full of a murky greenish liquid. “I almost forgot. I picked this up to save Sabine a trip.”

“Is that...?”

“Yeah. She said not to touch it until you dilute it. We’re supposed to use this.” He dug in his other pocket and came up with a small plastic medicinal dropper. “But for the record, I don’t approve of you ingesting Netherworld substances. Especially untested Netherworld substances. So I really have no choice but to hang out until the effects have completely worn off. To make sure you’re safe.”

I laughed. “My dad and Em are here.”

He lifted one pale brow. “And, naturally, you’re going to tell your dad what you’re up to...?”

I tugged him closer until I could whisper against his cheek. “I thought we agreed there were some things he doesn’t need to know about....”

“We did.” His hand slid beneath the hem of my shirt, and the dropper grazed my side. “Those are my very favorite things.”

“You know, when it’s silent in there, I get suspicious!” my dad called from the living room. Em laughed. Tod groaned.

He held me for another second and I breathed in his scent, then let him go and took my water glass from the desk, where I’d set it. I stared down into it, then at the vial. “This is not going to mix well.” I pulled out my rolling chair—itwouldn’t go far, with Em’s bed in the way—and sank into it, then set the glass down again while Tod worked the plug from the vial.

“You sure you want to do this?”

“No. But I can’t give it to Sophie if I’m not willing to try it myself.”

He stuck the tip of the dropper into the vial and drew up a quarter of an inch of murky green gunk. “My mom calls that the baby food test.”

“Baby food?”

“Yeah. When we were little, she wouldn’t give us anything to eat until she’d tasted it herself. Which is why she started baking. Evidently baby food is vile.”

I watched as he dropped into a squat, so that he was eye level with my glass. “So you really did grow up on cookies and cake. I knew it.”

“That’s why I’m so sweet now. I have no idea what went wrong with Nash.” He carefully squeezed the bulb at the top of the dropper, and a single drop of concentrated liquid envy plopped into my glass. For a second, it hung suspended in the water. Then tiny threadlike feelers of dark, dark green stretched out from the drop in all directions, bleeding slowly into the rest of the glass while Tod squirted the rest of what he’d sucked up back into the vial.

In seconds, the drop was gone and my water was an uneven green, paler than the concentrated color. Like an old bruise.

“Yuck.” I held the glass up to the light, and the green grew paler. “Maybe we should have mixed it with soda.”

Tod opened his mouth, and I took the first sip before he could offer to drink it for me. To test it on himself. The last thing I needed was for him to develop an irrational envy. The only person he could possibly be jealous of was Nash, and it had taken me forever to get the two of them back on speaking terms. Backward momentum was not okay.

“Yuck!” I made a face and wished for a cookie to rid my mouth of the foul film. “Envy tastes bitter.”

Tod laughed. “I could have told you that without even trying it. You gulp that, and I’ll get you something sweet to chase it with.”

“Thanks.”

I made myself drink the whole glass while he was gone, then made a mental note to warn Sabine to put it in something dark and sweet. Definitely coffee or soda. Or artificially sweetened diet protein shakes.

As I was swallowing the last mouthful, Tod reappeared in my room with a clear plastic cup of pink lemonade from my favorite burger place, a block from school. “Thanks.” I set the empty glass down and gulped a quarter of the lemonade through the straw without even taking the cup from him. “Much better.”

He set the drink on my nightstand, then sank onto my bed and scooted back until he could lean against the wall. I sat in front of him, my back pressed against his chest, and his arms wrapped around me. “Feel anything yet?”
