A message from the new editor, Claire Hennessy at Penguin Ireland tells me to spread the word that they are actively seeking children’s and YA submissions at the moment, particularly fiction for 7+.
As with all submissions to publishers, agents or magazines, read the submission requirements very carefully and adhere to them to the letter.
We strongly encourage submissions via email, to: firstname.lastname@example.org.
If you wish to submit electronically, please send a Word document consisting of a cover letter, short synopsis (no more than 500 words) and the work itself. The cover letter should include a brief summary of your book (a couple of sentences – not a synopsis) and a short note on yourself. Please do not send separate documents: all three elements should be included in a single document.

Also do your homework, what else have they published recently?
So if you have something, buff it up and send it to Claire.
