Disclaimer: I don't own Criminal Minds or The Dark is Rising Sequence.

I have a few one shots written up for this couple, mostly snippets, some longer, one smutty. I was debating posting them in the order I wrote them, but opted for chronological order instead. If I have to rearrange chapters I'll mark them clearly so you know which is the new material. The story is marked as complete because I may or may not continue to write for them, but I had enough material collectively to justify posting it. I hope you enjoy!

After almost a full month of nearly back to back cases, Spencer Reid finally had some time to visit his favorite used bookstore. Enjoying the sunshine of the crisp January day, he walked the few short blocks and found himself in his haven once again.

"Ah, the young doctor!" called the owner, Frederick, from behind the counter. "Haven't seen you in some time! How are you doing these days?"

"Hi, Freddy," Spencer said with a wave and a smile. "I'm well, work has been incredibly busy. How have you been? Anything new come in lately?"

Spencer liked Freddy Langan. He was very young for his 55 years, and a genuinely kind and funny man. He cared about Spencer, asking after his health and sleeping habits, and appeared to worry when he was absent for long stretches of time. It was almost fatherly, and Spencer appreciated it. Freddy seemed to be in an especially jovial mood today.

"Something new has come in, just not books!" Freddy laughed. "My daughter has finally moved home to help her old dad run the shop. Junior! Come meet our best customer!" he called to the recesses of the store.

A young woman that looked to be a few years younger than Spencer came from around the stacks, wearing the same green eyes and grin as her father. "Winifred, this is my friend Dr. Spencer Reid."

"The famous FBI genius, huh? You don't have to call me Winifred - Freddy will do just nicely. Or Junior, since you already know my dad by that name." She held her hand out to shake, a gesture he accepted as he looked her over.

The eyes were her father's, as was the curl to her hair, but the dark brunette color must come from her mother. His eyes were drawn immediately to the dreadlocks he could see dotted among the rest of her hair, sporting a couple of beads and some brightly colored string. It was a surprising contrast to the smooth curls, one that drew Spencer's eye and he actually found himself liking.

"I didn't realize my reputation preceded me."

"Oh, you're Dad's favorite," she said. "He keeps insisting you keep this place afloat, I'm surprised it took us this long to meet."

Spencer's cheeks colored. He did spend an obscene amount of his paychecks here. "Sorry to have kept you waiting, it's nice to meet you, Junior."

"You too, Spencer," she smiled. Turning to her dad, she asked, "What else do you need me to do? I've got the back room all organized, finally."

"I have some paperwork to handle, just hold down the fort for now," Freddy Senior answered. "You two enjoy yourselves," he smiled at them, disappearing through his office door.

"Daddy..." the younger Freddy murmured even though he was already out of earshot, shaking her head at the closed door.

"...is everything okay?" Spencer asked after a moment. The woman turned back to him, an exasperated smile on her face.

"Everything is fine, I just know him better than he thinks I do," she said. "So, Dr. Spencer Reid - what are we in the market for today?"

Spencer thought for a moment. "Nothing in particular, actually, mostly just browsing. I haven't been in for a few weeks, I sort of just missed this place. Do you have any recommendations?"

Freddy looked him up and down, brow furrowed. "Depends. How strict are you about intended age demographic? Something geared more towards younger readers?"

"Honestly, if it's a well written story I don't much care who it's intended for."

"Welsh and Arthurian mythology?"

Spencer smiled. "My mother was a professor of 15th century literature, and Arthur is a particular favorite of hers."

Freddy smiled back at him, moving from behind the counter and motioning for him to follow her through the stacks, letting her fingers trail over the spines. "Susan Cooper, The Dark is Rising Sequence. One of my childhood favorites, they're about good and evil and the forces behind them and the normal people like us who get caught up in their fight without ever really understanding it all. The language and imagery is beautiful, probably the kind of thing you'd appreciate from what Dad tells me. Aha!" They stopped at a particular shelf and she pulled a thick paperback volume down. "There we go, all five novels in one. Please let me know what you think of them, it's going to have quite the effect on my opinion of you. I'd hate for this friendship not to work out because you have lousy taste." She was grinning broadly now, only partially teasing. Spencer couldn't help the matching grin that spread across his face.

"Thank you Junior. I'm sure I'll love them."
