Pet Agents 2: To Track a Thief

Varkaan jäljillä

A new series for animal lovers!

Ti-bot has a bug that Kati-e can’t fix, so she sends him to an expert. Kati-e feels lonely without her friend but thankfully Tim’s home. Then Kati-e starts receiving messages about strange things that are going on in the neighbourhood: things that have gone missing from people’s homes.

When Ti-bot returns, he’s ready to help Kati-e investigate. The pair are so keen to solve the mystery that they hardly get any sleep. Then, in the middle of everything else, Kati-e gets a call from the zoo: a monkey has gone missing! And Ti-bot seems to know more than he’s letting on…

Riina and Sami Kaarla write and illustrate the Pet Agents series. As well as their four sons, their family includes two dogs and lots of cats. They have no shortage of pet adventures of their own!

“Children’s books about animals often train their readers to treat animals with respect. In the Pet Agents series, children interested in pets and other domestic animals also learn about their care and behaviour. The strength of the Pet Agents series lies in (…) its event-rich storytelling and abundant, colourful illustrations. (…) The children in the series are active, energetic and have a wide network of friends.”

“It’s a pleasure to follow the wonderful illustrations in these books. Their colour scheme is lovely and fresh. I like these children’s books very much anyway. They are high-quality, feel-good books.” Neverendingly blog

“There’s something for everyone in the Pet Agents book series, but the framework is so well-refined that it stays cohesive and interesting. (…) The book series has such an international feel that I had to check a couple of times that Pet Agents really is the work of two authors from here in Finland.” Lähiömutsi blog

“One of the best new children’s books that I have come across.” Yöpöydän kirjat blog
