Brock's Lost Lunchbox

by Della Cain, Kaytea Kat

Brock lost his lunchbox and found his new daddy.

After two years of working, working, and working, I finally get the promotion I’ve been waiting for. Silly me. I thought it would mean I could slow down. Instead, I’m practically living at work and haven’t been able to sneak away to Chained in far too long.

When a water main breaks and the entire office building is off-limits, I seize the opportunity and head straight to Little Night. Who cares if I only have a crop top and workout shorts. Little is a state of being, not the clothes.

It isn’t until I’m making a glittery mess that I discover my lunchbox fell out of my backpack in the parking lot and the sexy man returning it to me is 100 percent daddy. I wonder if he’d like to play. It’s not like I’m asking for forever. I’ve got too much work for that.

Brock’s Lost Lunchbox is a sweet age play romance featuring an overworked little who loses his lunchbox, the daddy who finds it, snuggles, cuddles, stuffies, footie jams, a memorable day at Chained, new beginnings, some old friends, true love, the one who got away, and a guaranteed happily ever after. If you like your romances on the Hallmark side but a bit kinkier, check out Brock’s Lost Lunchbox by USA Today Bestselling author Della Cain and her bestie and frequent partner in crime, Kaytea Kat.

I keep coming back to these stories even though they are just a bite of fluff but I get a kick out of them. This one was an improvement over past stories in that there was more dialogue and the storyline moved along nicely with the guys communicating with each other and not just telling the readers what was happening. So, it was enjoyable and short and sweet.

I really enjoyed reading Brock and Zeph’s story. Brock had been working hard for a promotion and was doing the work of two people, then when he got his promotion, the workload got even more intense and he was now working the job of three people. he was so busy working. He didn’t have enough time to go to his club, chained as often as he wanted. Then one night he was able to go and after doing his grocery shopping on the way to the club, he was digging through his car to find an outfit to wear, and his lunchbox accidentally fell out without his knowledge. Zeph was new to being a daddy, he was invited to go with his friend Will, as a guest to chained, that was where he met Brock and was able to return his lunchbox. The interaction between these two characters and enjoyed the development of their romance until eventually they both realised what they had, and go onto to live there, happily ever after.

I was thrown by the omega and mated since this is was not part of the series so far and not enough mentioned to think it really is part of this book. Something very clearly went wrong here. Lack of editing?

I remember those two instances. At the beginning and at the end. The first one threw me that much that I thought about DNFing it but I normally like that series as a little palate cleanser so I finished it.

Sadly I found this book lacking otherwise too. I sometimes wonder if this series should come to an end. The first few books I liked and they felt as if they had a bit substance. But lately it all feels/reads the same and is flat and very uninspired in my eyes.
I won't give it a star rating but perhaps I should quit reading this series.


Try it yourself it's entirely possible that I was just not in the right mood.

Brock works too hard and has no time to let his Little side out with his friends at Chained. When his work mandatorily closed, he decides to head to Chained where he meets Zeph, a new Daddy who found his lunchbox in the parking lot. This is Hallmark sweet with a practical side as they take their time yet still have lots of big time for the two businessmen. I received a copy of this through BookSprout and this is my voluntary opinion.

This was a really good book. I loved Brock and Zeph together. Brock is overworked and doesn’t get to go the Chained as often as he would like but the one night that he is able to go, he looses his lunch box. Zeph is a newer Daddy and is just visiting Chained with his friend and he was able to find Brock lunch box. These two hit it off very well and are able to work for their HEA. I really enjoyed this book and I am looking forward to the next one.

This is a delightful series; every book is a gift.
The characters are so sweet, they really complement each other.

This series really deserves to continue, and I hope many more installments will follow.

don't know why "omega" and "mate" were here while this is a contemporary book lol

🧸❤️ A Lost Lunchbox Leads Brock Straight to Zeph! ✨🥰

Brock’s Lost Lunchbox by Della Cain is such a sweet and comforting romance! I loved Brock and Zeph’s story and how something as simple as a lost lunchbox brings these two together at exactly the right time.

Brock has finally earned the promotion he worked so hard for, but instead of giving him more freedom, it has left him working constantly. He barely has time for himself anymore, much less time to visit Chained and embrace his Little side. When a broken water main unexpectedly closes his office building, he finally gets the chance to escape to Little Night.

I really liked Brock’s attitude that being a Little is about who he is and how he feels, not what he happens to be wearing. He doesn’t need the perfect outfit or circumstances to enjoy that part of himself. 🧸✨

Then Brock realizes his lunchbox has fallen out of his backpack—and Zeph is the sexy man who finds it and brings it back to him. Brock immediately picks up on Zeph’s Daddy energy, and suddenly that missing lunchbox doesn’t seem like such a bad thing after all. 😂❤️

Brock initially thinks there might be room for some fun with Zeph, but definitely not forever. He’s far too busy for that. Of course, feelings don’t always cooperate with carefully made plans, and I loved watching their connection become something much more meaningful.

There’s so much sweetness in Brock and Zeph’s relationship. The snuggles, cuddles, stuffies, footie pajamas, and their memorable time at Chained give the story such a cozy feel while the age-play element adds another layer to their connection. 🥰

I also enjoyed watching Brock begin to realize that there needs to be more to his life than constantly working. Zeph comes into his life when Brock desperately needs someone who encourages him to slow down, feel cared for, and make room for the things—and people—that make him happy. ❤️

At 160 pages, this is a quick and satisfying read with plenty of sweetness, comfort, romance, and steam.

If you enjoy M/M romance, Daddy/Little dynamics, age play, caring Daddy heroes, overworked Littles, cuddles, stuffies, comfort, new beginnings, and a romance with a sweet Hallmark feel and a kinkier twist, Brock and Zeph’s story is definitely worth reading. 🧸❤️

Absolutely 5 stars! ⭐⭐⭐⭐⭐.

Lost and Found

This is a sweet story with a happy ending, and a window into a little known or understood kink.

Brock is a hardworking man who is being taken advantage of by his employer. When people from his team leave, he’s often just expected to pick up their work in addition to his own. This leads to exhaustion, and a lack of time to socialize – especially with his fellow Littles at Chained, the local kink club. Zeph is a Daddy through and through whose last relationship ended badly because the man he was living with didn’t accept the dynamic Zeph needed.

Brock and Zeph meet the first night Zeph decides to join friends at Chained. Brock dropped his lunchbox in the parking lot, and Zeph brings it in intending to just return it to its owner. There’s some insta-love on Brock’s part; he really likes Zeph from the very beginning. Because Zeph is new to actual age play, there’s a bit of slow burn, and a date where they have a long discussion about boundaries, limits, and so forth. Zeph is quickly infatuated, indulging Brock’s Little fascination with stars and space, as well as encouraging him to find a way to reduce his increasing workload.

I particularly liked the clarity of when Brock was ‘Little’ or ‘Big’ – he was very definite about what activities were appropriate for him when he was Big, versus when he was Little.

I always enjoy these short, sweet, light-hearted, low angst stories of Littles losing something and finding a Daddy when it is returned. This time, Brock’s lunchbox falls out of his car when he is getting his little clothes out for a night at Chained. New Daddy Zeph is there with Brock’s little friend Sammy and his Daddy, Will, a friend of Zeph’s. The two spend some time playing together and the attraction is definitely there. Zeph would like to date Brock, but Brock’s work schedule hardly allows any time off for socializing. As Brock realizes changes need to be made if he wants to keep Zeph in his life, he works for a better work/life balance and more time for his Daddy Zeph.


The characters are so easy to relate to, you can feel the changes as Brock goes into little space, trusting his Daddy to protect and care for him, and you can also feel the growing love Zeph feels for this amazing man, big or little. I love when Brock comes out of little space by announcing “I’m big!”, meaning he is definitely ready for some spicy big person times. These stories are the perfect way to decompress after a busy or stressful day, or to just sit back and relax with two men enjoying their time together, kink or not. Always entertaining and engaging reads. More, please, Della!.

Hang on get comfortable you won’t be putting it down until the last page has been turned. Brock is a little but is doing the job of several people he has been working hard for a promotion, he earns the promotion but with that promotion he ends up doing the job of three people extremely tired, overworked, and a little heartbroken he hasn’t found the time to go to chained. But one evening after shopping he realizes he has time to go to the club but while looking for an outfit he loses his favorite lunch box of course it sends him into a tailspin. Zeph has known he was a daddy but never really acted on the impulse until he met up with a friend who convinced him to attend Chained with him as a guest, he found a lunchbox that belonged to one little and he intended to return it and the moment he met Brock he knew he needed guidance. The magnetic pull was there from the moment they met after returning his lunchbox they had the discussion about boundaries and limits. Zeph is quickly infatuated, indulging Brock’s Little fascination with stars and space, as well as encouraging him to find a way to reduce his increasing workload but where are they headed, will Brock accept the dynamic Zeph needs, will he help him learn to reduce his workload, and can they find happiness somewhere along the way?

Brock finally gets his long‑awaited promotion, only to end up busier than ever. When a water main break shuts down his office, he escapes to Little Night for a much‑needed break. There, a mysterious man returns Brock’s lost lunchbox — and Brock immediately senses the potential for a meaningful connection, even if he insists he’s too overwhelmed with work for anything long‑term.

This was a sweet story, just what I’ve come to expect from this series, with a cute little in Brock finding his forever Daddy in Zeph. Their meeting was adorable, full of charm and warmth, and the dynamic between them fit perfectly with the tone of the series. However, the story did suffer from a noticeable lack of editing — references to 'mates' and 'omega' popped up despite this clearly not being a shifter book, which pulled me out of the moment more than once. Still, the core relationship was lovely, tender, and full of the soft emotions this series does so well. This was an MM story with mature content and a BDSM-like DDLB dynamic.

I love how the world of Found by Daddy is both standalone and is so entwinned. Brock is Sammy's best friend (Sammy from the lost sailboat). He has a 70 + hour workday, and often misses playdates and Chained events due to exhaustion. Brock is sure that if he had a daddy, he would have a better life/work balance. A broken water machance to attend a little's night at Chained.
Zeph was a natural caregiver, but he wasn't sure he was a daddy. Invited by Will (Sammy's daddy) to a Chained little's event, he meets Brock.
They connect instantly. Zeph was the perfect daddy for him. There's sweet dates and then steamy nights. Some angst. Brock had an abusive partner and Zeph had an entitled one. So the pace is slow and gentle. Little Brock is totally adorable, a real Glitter Monster.
A quick, fun read. Seems like the authors are adding more friends to the little's group. So this series isn't finshing too soon. Yay.

Who knew that being a workaholic who drops their lunchbox in the car park of the kink club they love to attend (when they have time) would lead to true love, to a little finding their daddy?

Well, I suppose if you've been reading Della Cain's 'Found by Daddy' series it might not come as a complete surprise, but, very much like the room set aside especially for the littles and all the fun activities Miss Lilly always has on offer, each book in the series is a delight, a treat, a surprise and a wonderful romance.

If you like your books on the really cute side, love to read about daddy's who would do just about anything to keep their little's happy and a group of friends who love dino nuggies, colouring books and movies as well as glitter - there always has to be glitter - then you will love meeting Brock, discovering how he dropped his lunchbox, who found it and whether the end result will be true love. I may have melted my heart a little more with each book in this adorable series!

This is the 21st book in the Found by Daddy series. Each book can be a standalone read and features a different couple. This is the story of Brock and Zeph. Brock is a little and he is also overworked. He has no life/work balance at all. Since his new promotion, he is working all the time. Zeph is a new daddy and a guest at Chained; the local kink club. The two meet when Zeph finds Brock's lunchbox in the parking lot. It had fallen out while Brock was scrambling to put a little outfit together before going in. A burst pipe at work allowed him an early day for a change. This is their story. The book is well written and easy to read. It is a short, light hearted, no angst romance. I liked how sweet Brock and Zeph were together. As Zeph is new to the Daddy world, it created a slow burn dynamic which I enjoyed. Another sweet story in this series.

So, I don't expect books in this series to be perfect, but I do expect the editing to be good enough for me to not randomly see the terms "mated" or "omega" in a contemporary, non-omegaverse story. (As it happens, I think the word "mate" was used in place of "fiancé" in Rowan's book as well.) Also, I get that this series is set up to introduce characters who will be MCs later on, but these last few were a bit strange in how they did this: first, in Rowan's book, it was obvious that his bestie was Sammy; then, in Sammy's book, he seemed to be trying to depend on his friend Brock, the workaholic, more because Rowan wasn't single anymore; but now in Brock's book, he said it used to be just him and Sammy depending on each other before Sammy found a Daddy as if he and Sammy were besties. But the biggest thing about Brock is that he worked way too much and rarely spent time with his friends or at Chained, so it isn't likely that he actually had a bestie.

I loved this book! Brock and Zeph find each other through mutual friends and it all begins with a lost lunchbox. Brock works too hard and has very little time to spend being little and with friends. Zeph is new to being a Daddy but is sure he is one. When Brock’s office has a water main break, he gets some unexpected free time that will lead him to a night at Chained with his friend Sammy and Sammy’s Daddy Will. Zeph is a friend of Will’s and joins them at Chained on a guest pass for the night and he will find Brock’s lunchbox in the parking lot. The relationship between the two start off slowly but after the exchange of a few notes and small gifts, they find they fit together well and it is the beginning of a wonderful relationship full of love, little things and finding balance in life.

So cute...so sweet...Brock and his lunchbox...These little/daddy stories are such a enjoyable read. Two people like minded getting together over something that brings a lovely romance. Zeph was the daddy that Brock needed...nurture care and direction...someone that can ground him and show there's more to life than work work work. Brock has his besties but its always nice to have a daddy too by your side...which he found in Zeph....same with Zeph...Brock brought joy and love that he was missing from his past relationships...lovely romance...nice ending...I highly recommend if you love his serious and love little/daddy romances.

Zeph (daddy) + Brock (little)
This book definitely had a different vibe from previous books. It felt like Zeph was learning how to be a daddy. Zeph was a daddy that didn't take charge in the beginning. Zeph was hesitant in when to intervene for Brock's well being and sought other Daddies help. Compared to Brock who was more established as a little but new to having a Daddy. In a sense this daddy/little relationship was a beginners guide to this kind of relationship. I would recommend this book for readers looking to read their first daddy/little relationship.

Brock was a workaholic who barely had time for friends, let alone going to the gym. When a water main broke at his job and he was forced to leave the building, he decided to go to the gym and meet up with his friend Sammy. That is where he met Zeph, because Zeph had found his lunch box in the parking lot. What started out as a casual encounter and some playtime turned into sweet gifts and sweeter phone calls, leading to a beautiful relationship. I would like to know if the gym they went to is an actual location because it sounds fun.

Brock has a huge problem with his work life balance. He rarely has time to indulge his Little side. Zeph is just understanding what he truly wants in a partner. The fact that he's the one who finds Brock's lunchbox is the perfect start to something they both need and want. As with all the "Lost" stories, it's good and sweet and romantic and I really enjoyed it!! I voluntarily reviewed a complimentary copy of this book.

Nice! Brock is a workaholic who thinks his dedication and commitment will be rewarded. He is a little who struggles to find time to be little. Zeph, thinks he's a Daddy but wants to gather more information. He finds a lunchbox in the parking lot and brings it into Chained. Their relationship journey is sweet and well paced. Great story, always nice to see old friends and how their relationships are progressing. Zeph, is delightful. Cute cover art, nicely done!

Great new book in the series

Great new book in the series. Only one comment is that a few places mate rather than boyfriend was mentioned and later Brock was referenced as "omega".

I've loved this series and can't wait for the next one. I'm going to be sad when it's complete and no new friends will be coming.

Sweet, low angst story about Brock and Zeph. Brock is a little with way too much going on at work, and a promotion that just makes things worse. When he drops his lunchbox, Zeph finds it and brings it back to him.

This series is full of similar stories, quick romances with littles needing to find their daddy and this was another example of a fun and refreshing story.
